CVE Severity Published▾ Status Exploitation Description
CVE-2026-108699 High 2026-10-11 Not applicable Proof of concept only hyper-mcp through 0.8.3 contains an improper signature verification vulnerability that allows attackers to load malicious WebAssembly plugins because cosign_verify_args() accepts any signer identity and OIDC issuer by default. Attackers controlling a plugin image reference can sign a malicious image with a free Sigstore keyless certificate to execute plugins with configured host, filesystem, and environment capabilities.
CVE-2026-86405 Critical 2026-10-09 Not applicable No public exploit Improper verification of cryptographic signature vulnerability in Sipay Electronic Money and Payment Services Inc. PrestaShop Virtual POS Module allows Signature Spoofing by Improper Validation. This issue affects PrestaShop Virtual POS Module: from 26.8.1 before 26.9.1.
CVE-2026-85531 Critical 2026-10-09 Not applicable No public exploit Improper verification of cryptographic signature vulnerability in Sipay Electronic Money and Payment Services Inc. OpenCart Virtual POS Module allows Signature Spoofing by Improper Validation. This issue affects OpenCart Virtual POS Module: from 26.8.2 before 26.9.1.
CVE-2026-106581 High 2026-10-09 Not applicable No public exploit Before 4.92.0, Docker Desktop for Windows did not verify the signature of a package supplied to Docker Desktop Installer.exe install -package. An attacker able to provide a crafted package and convince a user to approve the Docker-signed UAC prompt could execute attacker-controlled installer actions as LocalSystem.
CVE-2026-103329 Medium 2026-10-09 Not applicable No public exploit The Super Payments WordPress plugin before 1.43.1 does not properly verify the authenticity of incoming payment webhook notifications, as the signing key used to validate their signature is empty by default, allowing unauthenticated attackers to forge a valid signature and mark arbitrary WooCommerce orders as paid without payment.
CVE-2026-84271 High 2026-10-08 Not applicable No public exploit IBM Guardium Data Protection 12.2 is vulnerable to a signature verification bypass in the patch installer. An attacker with local access could exploit this vulnerability to execute arbitrary code with root privileges.
CVE-2026-14999 High 2026-10-08 Not applicable No public exploit IBM DataPower Gateway 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 could allow a remote attacker to bypass authentication by forging valid JSON Web Signatures due to improper verification of cryptographic signatures.
CVE-2026-14497 High 2026-10-08 Not applicable No public exploit IBM DataPower Gateway 10.5.0.0 through 10.5.0.22, 10.6.1 through 10.6.6, 10.6.0.0 through 10.6.0.10, and 11.0.0.0 through 11.0.0.2 could allow a remote authenticated attacker to bypass security restrictions due to improper verification of cryptographic signatures.
CVE-2026-107724 High 2026-10-08 Not applicable Proof of concept only fast-jwt provides fast JSON Web Token (JWT) implementation. In 6.2.4, fast-jwt can classify raw serialized public JWK or JWKS JSON as an HMAC secret because src/crypto.js performDetectPublicKeyAlgorithms treats non-PEM strings as symmetric key material. If HS256 is explicitly allowed or inferred, an attacker who knows the exact serialized public-key bytes can use those bytes as an HMAC key and create a token containing arbitrary claims that createVerifier accepts. Serialization ordering or whitespace differences can prevent exploitation, and applications using supported PEM keys with an asymmetric-only algorithm allowlist are not affected. This issue is fixed in version 6.3.0.
CVE-2026-107722 Critical 2026-10-08 Not applicable Proof of concept only fast-jwt provides fast JSON Web Token (JWT) implementation. From 6.2.0 until 6.3.0, fast-jwt can misclassify RSA public-key text as an HMAC secret when the key has non-whitespace content before its PEM header. In src/crypto.js, performDetectPublicKeyAlgorithms trims whitespace but publicKeyPemMatcher remains start-anchored, so comments, control characters, zero-width characters, or wrapper text can prevent PEM detection and reach the HMAC fallback. An attacker who knows the public key bytes can sign arbitrary HS256 claims with that public material when HS256 is inferred or allowed, resulting in authentication or authorization bypass. An asymmetric-only algorithm allowlist prevents the attack. This issue is fixed in version 6.3.0.
CVE-2026-107720 High 2026-10-08 Not applicable Proof of concept only fast-jwt provides fast JSON Web Token (JWT) implementation. Prior to 6.3.1, fast-jwt createVerifier accepts an unsigned JWT when key is an empty string or null and algorithms is a non-empty allowlist. Falsy synchronous keys bypass prepareKeyOrSecret, allowedAlgorithms remains active, hasKey is false, and the empty signature avoids the verifySignature gate. An attacker can therefore submit a token containing arbitrary claims without possessing a signing key, resulting in authentication or authorization bypass. Claim validators still run, and non-empty keys, an empty key without algorithms, and the async key resolver path do not have this behavior. This issue is fixed in version 6.3.1.
CVE-2026-76482 Critical 2026-10-07 Not applicable No public exploit As part of Cisco's ongoing commitment to proactive security and product quality, the engineering team for Cisco License On-Prem, formerly Cisco Smart Software Manager On-Prem (SSM On-Prem), has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-76482 are related to issues with improper input verification that are grouped under the Common Weakness Enumeration (CWE) Pillar CWE-347.
CVE-2026-79807 High 2026-10-06 Not applicable No public exploit A missing integrity verification vulnerability in the Windows client software for ClearPass Policy Manager could allow malicious users on a local instance to elevate their user privileges. A successful exploit could allow these users to execute attacker-supplied code with elevated privileges on the local system.
CVE-2026-25302 High 2026-10-06 Not applicable No public exploit Cryptographic Issue when processing non-ELF partitions, authentication and signature checks are bypassed, allowing unsigned or corrupted images to be mounted and processed.
CVE-2026-78860 High 2026-10-05 Not applicable Proof of concept only An issue in Mercusys AC12 V2 allows a local attacker to execute arbitrary code via the storage of information in plaintext
CVE-2026-77805 High 2026-10-05 Not applicable No public exploit In Progress® Telerik® Fiddler® Classic for Windows, versions prior to v6.0.20262.10021, the integrity check applied to the external helper tools launched by the application is insufficient. Before executing a helper tool, the application only verifies that the file carries a valid Authenticode signature whose certificate subject name matches a broad allow list of publisher name fragments, rather than verifying that the file is the specific executable shipped with that version of the product. A local threat actor with low privileges who replaces one of these helper executables with any other validly signed binary from an allow-listed publisher can cause the substituted binary to be executed by the application, including with Administrator privileges for the tools that request elevation, resulting in privilege escalation and execution of unintended code. Successful exploitation requires the user to launch the affected external tool and to approve the elevation prompt without noticing that it refers to a different executable.
CVE-2026-105161 Medium 2026-10-04 Not applicable No public exploit A flaw has been found in invariant-systems-ai aiir up to 1.7.0. The affected element is an unknown function of the component Policy Gate Handler. Executing a manipulation can lead to improper verification of cryptographic signature. The attack can be executed remotely. It is advisable to upgrade the affected component. The GitHub repository of this project is not available anymore. This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2026-71891 High 2026-10-03 No exploit published No public exploit In Bouncy Castle for Java before 1.86, BLS12_381BasicScheme.keyValidate, and so BLSPublicKeyParameters and every BasicScheme, MessageAugmentation and ProofOfPossession verify and aggregateVerify that gate on it, accepted a public key built on a foreign ECCurve that merely shares BLS12-381's field characteristic. The prime-order subgroup check trusts a point's own curve to name its cofactor, since ECPoint.satisfiesOrder returns true outright when the curve's cofactor is one, so a point on a curve with a different equation and a cofactor forged to one passed keyValidate despite not being a G1 point at all. In BC's pairing implementation such a point contributes the identity in the target group, so an aggregate signature verified against a set of public keys including it is accepted even though it contains no signature for that key and message pair, admitting a phantom signer. keyValidate now first confirms that the point's curve carries exactly the canonical G1 field, equation, order and cofactor before any subgroup check. The issue is reachable only where an application constructs an ECPoint on an explicit, non-canonical curve and accepts it as an authority-bearing key; the standard 48-byte compressed-point decoder always supplies the canonical curve and was never affected.
CVE-2026-71887 High 2026-10-03 No exploit published No public exploit In Bouncy Castle for Java before 1.86, the high-level OpenPGP API accepted a data signature made by a signing subkey whose Subkey Binding signature carried no embedded Primary Key Binding (cross-certification) signature, in the case where that binding omits a Key Flags subpacket. RFC 9580 sec. 5.2.1.8 and sec. 10.1.3 require the embedded Primary Key Binding signature on any subkey that can issue signatures; it is the subkey's own statement that it belongs to the primary key it is bound under. OpenPGPCertificate resolved the subkey's key flags two different ways. isSigningKey() goes through getKeyFlags() and getApplyingSubpacket(), which falls back to the primary key's direct-key or primary User ID self-signature when the binding signature omits the subpacket, so the subkey inherited the primary's SIGN_DATA and counted as signing-capable; verifyEmbeddedPrimaryKeyBinding(), which enforces the requirement, reads the binding signature's own hashed subpackets, found no SIGN_DATA there, and returned early as a non-signing key without ever demanding the back signature. The same subkey was therefore signing-capable - so its signatures were attributed to the certificate and OpenPGPSignature.OpenPGPDocumentSignature.isValid() returned true - while being exempt from cross-certification, where GnuPG refuses the identical certificate and message. An attacker needs only the victim's public signing subkey, which is public material: they bind it to their own primary key with a Subkey Binding signature they are able to make, carrying no Key Flags and no embedded Primary Key Binding signature, which they cannot make without the subkey's private key, and a relying party verifying one of the victim's genuinely signed messages against that certificate is told the signature is valid and given the attacker's certificate as its issuer. Because a certificate's User IDs are self-asserted, a verifier that pins on the subkey's fingerprint or key ID while taking the identity from the enclosing certificate reports a real signature under an attacker-chosen identity. This is misattribution of a genuine signature rather than forgery of a new one: no private key is recovered, and the signature must be one the grafted subkey actually made. The low-level PGPSignature / PGPPublicKeyRing API performs no binding checks by design and is unaffected. Key Flags are a statement about the key the carrying signature refers to (RFC 9580 sec. 5.2.3.29), so a subkey no longer inherits them from the certificate-wide signatures of the primary key: a Subkey Binding signature that omits the subpacket now leaves the subkey with no capabilities rather than the primary's, which makes the flags the cross-certification check consults the same flags every other decision consults. Preferences and the other subpackets a direct-key signature carries are inherited as before, and the primary key itself, whose flags legitimately come from its own direct-key or User ID self-signature, is unaffected.
CVE-2026-105118 Low 2026-10-03 Not applicable No public exploit OpenAM before 16.1.3 contains an open redirect vulnerability that allows unauthenticated attackers to redirect users by supplying an unverified id_token_hint to the /oauth2/connect/endSession endpoint. Attackers can name any realm client in a forged hint to redirect victims to any registered post-logout URI, enabling phishing that borrows the OpenAM host's trust.
CVE-2026-86326 High 2026-10-02 Not applicable No public exploit An improper verification of cryptographic signature vulnerability exists in protocol gateways because the device does not properly verify the cryptographic authenticity of firmware images before installation. An attacker with high privileges and access to the firmware update interface could provide a specially crafted or modified firmware image, causing it to be installed on the device. Successful exploitation could allow the attacker to execute unauthorized code, compromise the integrity and availability of the device, and persist malicious modifications across subsequent firmware updates.
CVE-2026-63571 High 2026-10-02 Not applicable No public exploit Improper verification of cryptographic signature in the attribute certificate path validator (PkixAttrCertPathValidator, also used by PkixAttrCertPathBuilder) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker to have a forged X.509 attribute certificate accepted as valid, and so obtain whatever roles or privileges an application grants on the strength of its attributes, via an attribute certificate that names a trusted attribute authority as its issuer but was not signed by it, because the RFC 3281 validation steps check the holder and issuer certification paths, validity period, extensions and revocation status but never verify the attribute certificate's signature with the issuer's public key. Only applications that use these classes to validate attribute certificates are affected.
CVE-2026-104437 High 2026-10-02 Not applicable Proof of concept only Zebra before 4.4.0 contains a consensus divergence vulnerability in V5 transparent signature verification, computing a ZIP-244 digest for SIGHASH_SINGLE inputs lacking corresponding outputs instead of failing. Attackers can craft V5 transactions with fewer outputs than inputs that Zebra accepts and templates via getblocktemplate, producing blocks zcashd rejects.
CVE-2026-104435 High 2026-10-02 Not applicable No public exploit Zebra zebrad 4.4.0 and zebra-script 6.0.0 fail to enforce a ZIP-244 consensus rule, accepting V5 transparent inputs signed with SIGHASH_SINGLE that lack a corresponding output. Attackers can broadcast crafted V5 transactions with more inputs than outputs that Zebra accepts but zcashd rejects, causing a network consensus split.
CVE-2026-94212 Medium 2026-10-01 Not applicable No public exploit Improper verification of cryptographic signature vulnerability in Apache APISIX. Any unauthenticated attacker could impersonate any user on every route protected by the saml-auth plugin under default configuration. This issue affects Apache APISIX: from 3.17.0 through 3.18.0. Users are recommended to upgrade to version 3.19.0, which fixes the issue.
CVE-2026-18397 Critical 2026-10-01 Not applicable No public exploit This vulnerability enables unauthenticated remote code execution (RCE) on a victim's machine by exploiting a combination of cryptographic weaknesses and memory management issues in the SConnect native host component. The attack leverages an unrestricted messaging interface between an attacker-controlled web page and the native host, allowing malicious input to bypass security checks.
CVE-2026-103245 Medium 2026-10-01 Not applicable No public exploit n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 fail to verify the x-webflow-signature HMAC in the Webflow Trigger node webhook handler. Unauthenticated attackers can send forged webhook requests with attacker-controlled payloads to trigger workflows and manipulate downstream actions like record creation or API calls.
CVE-2026-87004 High 2026-09-30 Not applicable Proof of concept only Tugtainer is a self-hosted app for automating updates of Docker containers. Prior to version 1.31.3, when the OIDC login flow completes, backend/modules/auth/providers/auth_oidc_provider.py decodes the id_token returned by the identity provider's token endpoint using jose.jwt.get_unverified_claims() instead of jwt.decode(). This skips signature verification, audience (aud) validation, issuer (iss) validation, and expiry (exp) checking entirely. The extracted claims (email/sub/preferred_username) are then used directly as the user_id for the resulting Tugtainer session. This issue has been patched in version 1.31.3.
CVE-2026-55174 Medium 2026-09-30 Not applicable Proof of concept only UltrafastSecp256k1 is a high-performance, multi-backend secp256k1 engine with reproducible audit evidence, compatibility shims, and profile-based review scopes. Prior to version 4.2.0, UltrafastSecp256k1's ECDSA adaptor pre-signature verification accepts forged adaptor pre-signatures whose "r" value is not cryptographically bound to the adaptor point "T". This issue has been patched in version 4.2.0.
CVE-2026-47554 High 2026-09-30 Not applicable No public exploit NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer where improper verification of cryptographic signatures may cause signature verification to be bypassed under memory pressure. A successful exploit of this vulnerability might lead to denial of service and data tampering.
CVE-2026-102508 Critical 2026-09-30 No exploit published No public exploit Improper Verification of Cryptographic Signature and Improper Certificate Validation in the OPC UA driver of Apache PLC4X (PLC4J) allows an attacker in a network position between client and server to impersonate the OPC UA server and to read, forge or modify secure-channel traffic, including user credential ssent by the client. The defect manifests differently depending on the version: - In 0.9.0 through 0.11.0 a failed message-signature check is only logged and never enforced, and there is no mechanism to verify the server certificate: it is taken from the unauthenticated GetEndpoints discovery response and used to encrypt the user's password. - In 0.12.0 through 0.13.1 the signature check is inverted (valid signatures are rejected, invalid ones accepted), and server certificates are accepted without a trust anchor by default. - In all affected versions the default security policy is None. Starting with 0.12.0 the driver additionally continues silently at a weaker security policy than the one configured, and starting with 0.13.0 endpoint selection prefers the weakest matching endpoint. Users checking only for one of these mechanisms may wrongly conclude they are unaffected. This issue affects Apache PLC4X: from 0.9.0 before 1.0.0. Users are recommended to upgrade to version 1.0.0, which fixes the issue. Version 1.0.0 verifies message signatures correctly, refuses to connect unless the server certificate can be verified against a configured trust store or pinned certificate, defaults to Basic256Sha256 with SignAndEncrypt, and fails the connection if the negotiated security policy is weaker than the configured one.
CVE-2026-91191 High 2026-09-29 Not applicable No public exploit The device's update mechanism includes conditions that allow unauthorized software packages to be accepted as authentic. During the boot process, the stock done function disables signature verification in the OPKG configuration before restoring optional packages from a writable, unsigned feed. Separately, the publicly distributed SDK contains the production private key whose corresponding public key is trusted by both stable and beta firmware builds. Either issue undermines package authenticity, and together they allow an attacker to provide packages that appear valid to the system. Even if signature enforcement is restored, the exposed production key enables an attacker to generate signatures that the device will continue to trust. An attacker who can supply a malicious package may be able to execute arbitrary code with root privileges during installation.
CVE-2026-100293 High 2026-09-29 Not applicable No public exploit In Anjvision YSSD‑RTMP‑H5 firmware version 3.3.2.4, both the local and cloud update mechanisms apply new firmware without any cryptographic verification, relying only on basic hashing. This design allows an attacker who can reach the update routine to introduce untrusted firmware images that the device will accept as valid.
CVE-2026-96760 Critical 2026-09-28 Not applicable No public exploit Authlib (v1.8.0 and below) contains a signature verification bypass vulnerability. The JsonWebSignature.deserialize_json() method accepts a JSON Serialization JWS object and returns the payload as successfully verified without checking for a signature and without requiring a cryptographic key.
CVE-2026-102273 High 2026-09-28 Not applicable No public exploit PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, PyJWT HMACAlgorithm.prepare_key is affected because HMAC key guard only recognizes top-level public JWK forms and misses container representations. This occurs when an application allows HMAC and asymmetric algorithms and passes a public JWK container as the raw key. As a result, public asymmetric key material is accepted as the HMAC secret. Consequently, an attacker who knows the public key can forge a token with arbitrary authenticated claims. This issue is fixed in version 2.14.0.
CVE-2026-102272 High 2026-09-28 Not applicable Proof of concept only PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.prepare_key in jwt/algorithms.py is affected because raw-JWK detector does not normalize accepted Unicode byte-order marks before checking for JSON. This occurs when a public JWK is prefixed with a UTF-8 BOM and used in a mixed-algorithm verification path. As a result, public JWK bypasses asymmetric-key detection and becomes the HMAC secret. Consequently, an attacker who knows the public key can forge authenticated tokens. This issue is fixed in version 2.14.0.
CVE-2026-102271 High 2026-09-28 Not applicable Proof of concept only PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.prepare_key is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and supplies a DER public key as the shared verification key. As a result, PyJWT uses public DER bytes as an HMAC secret. Consequently, an attacker who knows the public key can forge authenticated HMAC tokens. This issue is fixed in version 2.14.0.
CVE-2026-102268 Critical 2026-09-28 Not applicable Proof of concept only PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, is_pem_format in jwt/utils.py is affected because is_pem_format does not recognize every PEM representation accepted by the cryptography loader. This occurs when an application mixes HMAC and asymmetric algorithms and supplies a mutated public-key PEM as raw key bytes. As a result, HMACAlgorithm.prepare_key treats the unrecognized asymmetric public key as an HMAC secret. Consequently, an attacker who knows the public key can forge authenticated HMAC tokens. This issue is fixed in version 2.14.0.
CVE-2026-102266 Critical 2026-09-28 Not applicable Proof of concept only PyJWT is a Python implementation of JSON Web Token standards. From 2.13.0 until 2.14.0, HMACAlgorithm.from_jwk is affected because PyJWK verification path used the decoded key without applying prepare_key validation. This occurs when a trusted JWK Set contains an oct entry with an empty k value. As a result, an attacker signs an HMAC token with the same zero-length key accepted by PyJWT. Consequently, forged token can carry arbitrary authenticated claims. This issue is fixed in version 2.14.0.
CVE-2026-94418 Low 2026-09-27 Not applicable No public exploit Under WOLFSSL_SMALL_CERT_VERIFY, ProcessPeerCertParse() runs the certificate signature check separately from the parse to keep peak memory down, then merges the two results, but it merged the signature result back only when the parse returned 0, so any parse error hid it. ParseCertRelative() reaches its validity-date, name-constraint and critical-extension checks only after ConfirmSignature() has passed, so splitting the signature check out inverts the precedence that makes "override date errors" a sound policy, and ASN_SIG_CONFIRM_E is never surfaced anywhere. The attacker needs no key material from the real PKI and no CA compromise: a self-made certificate carrying the expected subject name, the trusted CA's subject as its issuer, arbitrary bytes where the signature goes, a validity window in the past and the attacker's own key pair is sufficient. Affected builds define WOLFSSL_SMALL_CERT_VERIFY, which is off by default, is not set implicitly by any platform or preset header, and is not reachable from any CMake option; the autotools routes are --enable-lowresource, --enable-leantls, --enable-tinytls13=cert and --enable-tinytls13=mutualauth, and examples/configs/user_settings_embedded.h reaches it through WC_CFG_SMALL_CERT_VERIFY, which ships as 0, while neither --enable-all nor --enable-distro enables it at all. The application must additionally install a verify callback through wolfSSL_CTX_set_verify() or wolfSSL_set_verify() with WOLFSSL_VERIFY_PEER that returns 1 for ASN_BEFORE_DATE_E or ASN_AFTER_DATE_E; wolfSSL ships this exact shape as myVerify() in wolfssl/test.h under VERIFY_OVERRIDE_DATE_ERR, which examples/client -D selects. An application with no callback, or whose callback returns preverify for date errors, still fails the handshake, and wolfSSL_CertManagerVerifyBuffer() and wc_CheckCertSignature() report ASN_SIG_CONFIRM_E correctly in the same binary. TLS 1.2 and TLS 1.3 are affected in both directions, and DTLS reaches the same function; where the forged certificate is a chain certificate the callback's consent causes it to be cached in the WOLFSSL_CTX certificate manager, so an exposed deployment must restart the context or the process rather than merely reconnect.
CVE-2025-71422 Medium 2026-09-27 Not applicable No public exploit Contrast is a Kubernetes runtime for confidential containers. In versions before 1.12.1, the secure persistent volume feature is vulnerable to a malicious host supplying a crafted LUKS2 volume to a pod VM. LUKS2 volume metadata is not authenticated and, with cryptsetup versions prior to 2.8.1, a header specifying the null keyslot encryption algorithm (cipher_null-ecb) is accepted without error. Because the Contrast Initializer assumes a device is protected if `cryptsetup open` succeeds with the secret seed, the guest will open the attacker-supplied volume and write secret data in plaintext, or under a volume key known to the attacker, allowing the host to read confidential data that should have been encrypted. Contrast v1.12.1 ships cryptsetup 2.8.1, which disables null ciphers in keyslots when the passphrase is non-empty; v1.13.0 adds detached-header validation in guest memory and integrity protection for secure persistent storage. Contrast persistent volumes were not integrity protected, so integrity impact is not considered.
CVE-2026-97732 Medium 2026-09-25 Not applicable No public exploit IRONMACE Ironshield 1.0.0.167 has a tvk.sys kernel-mode driver that authenticates client executables by checking for expected publisher and root-certificate strings in WIN_CERTIFICATE data ("IRONMACE Co., Ltd." and "DigiCert Trusted Root G4") instead of parsing and validating the PKCS signature data. As a result, a local unprivileged attacker may bypass this via crafted certificate data and obtain access to privileged IOCTL functionality.
CVE-2026-97731 High 2026-09-25 Not applicable No public exploit MinIO through 7aac2a2 does not verify that every x-amz-* header present on a request also appears in the client-supplied X-Amz-SignedHeaders list. extractSignedHeaders() in cmd/signature-v4-utils.go iterates only the claimed list and never enumerates the headers that actually arrived, and thus a header that arrives unsigned is neither hashed into the canonical request nor rejected. Because cmd/api-router.go dispatches CopyObject on the presence of x-amz-copy-source alone, the holder of a presigned PUT URL scoped to a single object can add that header to the unmodified URL and cause a server-side copy, executed as the signer, of any object the signing key can read. A grant to write one object becomes a read of every bucket that key can reach. Amazon S3 rejects the equivalent request with HTTP 403 AccessDenied. The minio/minio GitHub repository was archived in April 2026; pgsty/silo before 1233254 is also affected.
CVE-2026-84465 High 2026-09-25 Not applicable No public exploit Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when Zammad checks the digital signature on an incoming S/MIME-signed email, it does not verify that the signing certificate is genuinely trusted, it only checks whether a certificate with a matching name is already stored in the system. An attacker can create their own certificate using the name of a real, previously trusted sender and use it to send a forged email. Zammad will display that email with the same "validly signed" indicator as a genuine message from the real sender, even though the attacker never had access to that sender's actual certificate or private key. This issue is fixed in version 7.1.2.
CVE-2026-61855 Medium 2026-09-25 Not applicable No public exploit Zammad is a web based open source helpdesk/customer support system. In 7.0.3 and 7.1.1, under certain conditions, Zammad's verification of inbound PGP-signed email can mark a message as carrying a valid ("Good") PGP signature from a registered sender key, even though the displayed message content is not actually covered by that signature. As a result, the inbound article may be stored with a successful signature status that does not reflect the authenticity of the shown content. This can mislead agents who rely on the signature indicator when assessing the trustworthiness of incoming mail. This issue is fixed in version 7.1.2.
CVE-2026-56727 High 2026-09-25 Not applicable No public exploit Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary In Zammad's inbound PGP email processing, the return value of the gpg verification call was silently discarded. Regardless of whether gpg reported a valid, invalid, or missing signature, the handler unconditionally wrote sign: { success: true, comment: "Good signature" } to the article's security preferences. Impact Any sender could tamper with the body of a multipart/signed PGP email, or craft a message with an entirely fabricated or mismatched signature, and Zammad would display it to the recipient as cryptographically verified with a "Good signature" label. Users and agents relying on Zammad's signature indicator to confirm message authenticity and integrity would be misled into trusting modified or forged content. The vulnerability affects all inbound PGP-signed emails processed while the PGP integration is enabled. This issue is fixed in version 7.0.2.
CVE-2026-91187 Critical 2026-09-24 Not applicable No public exploit Improper Verification of Cryptographic Signature vulnerability in dashbit nimble_zta allows an unauthenticated remote attacker to authenticate as an arbitrary Cloudflare service token. Applications using the Cloudflare Zero Trust authentication strategy are affected. verify_token/2 in lib/nimble_zta/cloudflare.ex matches the result of JOSE.JWT.verify/2 against {_, token, _s}, which discards the boolean verification result and returns the decoded token after a failed signature check. The attacker sends a forged JWT in the cf-access-jwt-assertion header, carrying the expected iss claim and the seven service token claims. verify_iss/2 reads the iss claim from the forged token, so it rejects nothing, and the service token path then returns those claims as the authenticated identity. This issue affects nimble_zta: from 0.1.2 before 0.1.3.
CVE-2026-57178 High 2026-09-24 Not applicable No public exploit Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the `vk-app` backend accepted VK application callback data without verifying the callback signature when the `auth_key` parameter was omitted. Applications using this backend could treat unsigned attacker-controlled data as a verified VK identity. An attacker could choose callback fields such as `viewer_id`, `access_token`, `api_id`, and `api_result`, potentially allowing authentication as an arbitrary VK user ID. The issue affects only applications using the `vk-app` backend. The issue has been fixed in version 5.0.0 by requiring `auth_key` to be present and valid before callback data is trusted.
CVE-2026-91814 Medium 2026-09-23 Not applicable No public exploit A signature validation vulnerability exists in Foxit PDF Editor/Reader’s handling of incrementally updated PDF documents. Changes to visible document content may not invalidate the existing signature, allowing attackers to alter signed content and potentially carry out content spoofing while the document continues to appear validly signed.
CVE-2026-95503 Medium 2026-09-22 No exploit published No public exploit A flaw was found in the Kerberos federation provider of Keycloak, an open-source identity and access management solution. When Kerberos password authentication is used without SPNEGO, the system fails to verify the identity of the Key Distribution Center (KDC) by requesting a server ticket. This allows an attacker on the same network to spoof the KDC and bypass the authentication process, potentially gaining unauthorized access to user accounts.
CVE-2026-85995 High 2026-09-22 Not applicable No public exploit Notepad++ is a free and open-source source code editor. From 8.9.7 until 8.9.8, the Notepad++ updater and signature verification path can accept a modified GUP.exe file whose embedded certificate metadata remains present even though its Authenticode digest is invalid. An attacker who can replace or plant the updater-related file can cause Notepad++ to launch attacker-modified code when a user triggers the updater path, but the issue does not provide remote code execution by itself. This issue is fixed in version 8.9.8.
CVE-2026-18152 High 2026-09-22 Not applicable No public exploit IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to forge validly-signed messages due to improper verification of cryptographic signatures.
CVE-2026-94368 High 2026-09-21 Not applicable No public exploit A flaw was found in the signature verification logic of noobaa-core, the core component of the NooBaa Multicloud Object Gateway. The issue occurs when the service processes S3 presigned URLs using Signature Version 4 (SigV4). Due to improper validation, the service fails to reject requests containing unsigned x-amz- headers, instead simply dropping them from the signature calculation. This allows an attacker who possesses a valid presigned PUT URL to add an unsigned x-amz-copy-source header, effectively converting a simple upload into a CopyObject operation. This can lead to unauthorized access and copying of any data the original signer is permitted to reach across the entire storage system.
CVE-2026-75939 High 2026-09-21 Not applicable No public exploit A flaw was found in openshift/oc-mirror. The tool incorrectly verifies PGP (Pretty Good Privacy) release image signatures by checking for signature errors before the entire signed body is processed, leading to a bypass of the signature verification. A remote attacker, by intercepting or manipulating network traffic to the signature endpoint, could exploit this to craft a PGP message with a valid Red Hat release key ID but a forged signature. This enables the `oc-mirror` tool to accept and mirror a malicious release payload into a disconnected registry, potentially compromising the integrity of software deployments.
CVE-2026-9832 Medium 2026-09-19 Not applicable No public exploit The Payment Gateway of Stripe for WooCommerce plugin for WordPress is vulnerable to Improper Verification of Cryptographic Signature in all versions up to, and including, 5.0.8. This is due to the publicly accessible `woocommerce_api_wt_stripe` webhook endpoint (`EH_Stripe_Webhook_Handler::handle()`) wrapping the only call to `\Stripe\Webhook::constructEvent()` inside an `if (!empty($endpoint_secret))` guard that is never entered on default installations — because the `eh_stripe_webhook_secret` option is empty after a fresh plugin install — causing the raw, attacker-controlled POST body to be decoded and processed as a fully trusted Stripe event without any signature verification, authentication, or authorization. This makes it possible for unauthenticated attackers to send forged Stripe webhook events to manipulate WooCommerce order statuses, including marking unpaid orders as paid or completed via `payment_complete()`, forcing legitimate orders into a failed state, fabricating dispute notifications, and injecting forged refund events. This vulnerability is only exploitable when the Stripe webhook signing secret has not been configured by an administrator; once a valid signing secret is saved, `\Stripe\Webhook::constructEvent()` is enforced and forged requests are rejected.
CVE-2026-93657 High 2026-09-18 Not applicable No public exploit hickory-resolver versions before 0.26.2 fail to propagate bogus DNSSEC proof states through the Resolver::lookup() and Resolver::lookup_ip() APIs, allowing invalid records to be returned as successful results. Attackers controlling the answering zone or positioned on the network path can have forged DNS records accepted as validated, bypassing DNSSEC authentication checks.
CVE-2026-59163 Critical 2026-09-18 Not applicable Proof of concept only Mnemosyne is a memory layer for artificial intelligence agents. Prior to v3.10.1, the auth check in mnemosyne/core/sync_server.py parsed the JWT's header and payload using base64 decoding, then passed the token to a jwt library call with options that effectively disabled signature verification. The server accepted any well-formed token regardless of the signature, including tokens with alg: none and tokens signed with the wrong key. The fix in v3.10.1 replaces the broken decode with a from-scratch HS256 verifier using only the Python standard library. For users who cannot upgrade immediately, restrict network access to the sync server endpoint to trusted clients only. Firewall, reverse proxy with mTLS, or localhost bind with SSH tunnel are all viable. The vulnerability is not exploitable against an unreachable endpoint.
CVE-2026-28199 Medium 2026-09-18 Not applicable No public exploit An authenticated user with access to the NetBackup Flex OS management shell could read arbitrary files from the underlying operating system by supplying a specially crafted path argument to a diagnostic command. Successful exploitation could expose sensitive system configuration and credential material stored on the appliance.
CVE-2026-28198 Critical 2026-09-18 Not applicable No public exploit An authenticated, low-privileged user with access to the NetBackup Flex OS management shell could bypass the cryptographic signature verification step of a privileged support command by supplying a specially formed access credential. Successful exploitation grants the attacker an unrestricted root shell with full control over the Flex appliance host and all hosted containers, completely compromising confidentiality, integrity, and availability.
CVE-2026-86038 High 2026-09-17 Not applicable Proof of concept only libp2p is a JavaScript implementation of the libp2p networking stack. From 15.0.0 until 16.0.5, @libp2p/gossipsub uses the default StrictSign policy in packages/gossipsub/src/utils/buildRawMessage.ts, where validateToRawMessage verifies a signature with attacker-controlled msg.key but skips binding that key to msg.from when the claimed author is an RSA peer ID that does not inline a public key. An unauthenticated attacker can place a victim RSA peer ID in msg.from, sign the message with the attacker's private key, and supply the attacker's public key in msg.key, causing the message to be accepted and propagated as authored by the victim. Applications that trust message.from for validators, authorization, accounting, moderation, reputation, or audit logging can process attacker-controlled data under false origin attribution. The issue is fixed in version 16.0.5.
CVE-2026-78223 Medium 2026-09-17 Not applicable No public exploit Improper Verification of Cryptographic Signature vulnerability in team-alembic AshAuthentication allows a caller of the token revocation action to neutralise a revocation or write arbitrary rows into the token resource. AshAuthentication.TokenResource.RevokeTokenChange.change/3 reads the :token argument and decodes it with AshAuthentication.Jwt.peek/1, which delegates to Joken.peek_claims/1 and performs no signature check, unlike Jwt.verify/4. The jti, exp and sub claims it returns are written straight onto the revocation record, guarded only by byte_size(token) > 0. Because expires_at derives from the attacker-chosen exp, a forged copy of a genuine token that keeps the real jti but backdates exp yields a revocation row that is already expired: expunge_expired removes it and the genuine token passes revoked? again. Arbitrary jti and sub values can be inserted the same way. This issue affects ash_authentication: from 0.2.0 before 4.15.0 and from 5.0.0-rc.0 before 5.0.0-rc.14.
CVE-2026-54581 High 2026-09-17 Not applicable No public exploit mport is the MidnightBSD Package Manager. Prior to 2.7.8, the mport_fetch_bootstrap_index() function in libmport/fetch.c could return success when bootstrap index hash verification encountered a missing or invalid hash because the failure path did not preserve a fatal result. A network attacker or compromised mirror able to alter bootstrap index content or its transport path could therefore cause mport to proceed with an unverified or tampered bootstrap package index. This issue is fixed in version 2.7.8.
CVE-2026-92718 High 2026-09-16 Not applicable Proof of concept only Nuclei versions before 3.11.1 cache template signature verification based only on file modification time without content checksums. Attackers can replace verified templates with unsigned malicious content and restore the original modification time to bypass signature checks and execute arbitrary operating system commands.
CVE-2026-86585 High 2026-09-16 Not applicable No public exploit The lack of signature verification of firmware update packages in VEO and VEO-XS Wi-Fi monitors, in versions prior to 01.48.001, allows an attacker who controls the delivery of an update to install unauthorised firmware.
CVE-2026-86109 High 2026-09-16 Not applicable No public exploit The VeloCloud Edge software update workflow may accept update bundles without properly validating their signatures because the workflow does not restrict the digest algorithm used for artifact verification. An attacker with either sufficient privileges to upload packages to VeloCloud Orchestrator or credentials permitting direct access to an Edge may be able to install unauthorized software.
CVE-2026-42784 High 2026-09-16 Not applicable No public exploit A flaw was found in sequoia-openpgp. The library incorrectly infers key flags for older certificates when a key flags subpacket is missing, leading to a discrepancy in how key capabilities are viewed. This key flag confusion allows an attacker to bypass the back-signature check. Consequently, an attacker can illegitimately bind an arbitrary subkey to their own certificate and forge signatures, completely compromising cryptographic integrity.
CVE-2026-58200 High 2026-09-15 Not applicable No public exploit Payload Plugins is a collection of plugins designed to enhance Payload CMS. From 0.3.0 until 0.4.0, @jhb.software/payload-cloudinary-plugin deployments with clientUploads enabled expose POST /api/cloudinary-generate-signature, whose handler in cloudinary/src/getGenerateSignature.ts passes attacker-controlled body.paramsToSign directly to cloudinary.utils.api_sign_request without a key allowlist, collection policy, timestamp freshness check, or configured-folder enforcement. Any authenticated Payload user can obtain a valid Cloudinary HMAC-SHA1 signature for unauthorized parameters such as overwrite, type, notification_url, invalidate, folder, and public_id. The signature can authorize asset replacement, upload visibility changes, callbacks to attacker-selected URLs, cache invalidation, and uploads outside the intended folder. The client-visible Cloudinary API key is expected by the upload design, but the unrestricted server-side signature supplies the authorization value needed to complete these operations. This vulnerability is fixed in 0.4.0.
CVE-2026-87802 Critical 2026-09-14 No exploit published No public exploit Improper verification of cryptographic signature vulnerability in Apache Syncope. When SRA is configured for OAuth 2.0 without JWKS set URI assigned, an attacker can forge arbitrary JWTs to impersonate any user identity and permissions, gaining full access to services proxied by SRA. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.7, from 4.1.0-M0 through 4.1.2. Users are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.
CVE-2026-57122 High 2026-09-14 Not applicable No public exploit PraisonAI is a multi-agent teams system. Prior to 4.6.59, the WhatsApp and Linear bot webhook handlers verify HMAC signatures only when WHATSAPP_APP_SECRET or LINEAR_WEBHOOK_SECRET is configured and otherwise parse and dispatch unsigned request bodies. A remote unauthenticated client that reaches the webhook route can forge messages, comments, or agent-session events, impersonate platform users, influence agent prompts and actions, and disrupt bot processing. This issue is fixed in 4.6.59.
CVE-2026-54155 High 2026-09-14 Not applicable No public exploit node-opcua is an OPC UA implementation for TypeScript and Node.js. Prior to 2.166.0, the UserNameIdentityToken authentication handler in packages/node-opcua-server/source/opcua_server.ts decrypts an RSA-OAEP password blob but does not verify that the trailing bytes match the current session serverNonce. An unauthenticated remote attacker can obtain the server public key through GetEndpoints and forge a blob whose little-endian length produces an empty password passed to isValidUser, compromising accounts that accept an empty password. Missing nonce binding also allows a captured UserNameIdentityToken ciphertext to be replayed in another session, and SecurityMode=None removes the separate client-signature safeguard. This issue is fixed in version 2.166.0.
CVE-2026-89169 Medium 2026-09-11 Not applicable No public exploit live-boot ff8867c allows attackers to bypass the dm-verity-enforce-roothash-signature protection mechanism when the .verity file is missing.
CVE-2026-80469 High 2026-09-11 Not applicable No public exploit An attacker may achieve arbitrary code execution on a target system by uploading a malicious device driver package, bypassing driver verification mechanisms, and triggering the execution of attacker-controlled code. User interaction is required.
CVE-2026-73784 High 2026-09-11 Not applicable No public exploit A potential security vulnerability in HPE IceWall products could be exploited to tamper SAML response, allowing an attacker to impersonate another user.
CVE-2026-54248 Medium 2026-09-11 Not applicable No public exploit Doco-CD is a GitOps continuous delivery tool that automatically deploys and updates Docker Compose projects/services and Swarm stacks. Prior to version 0.90.1, a trust-boundary flaw in OCI artifact verification allowed artifact-provided deployment config to influence the policy used to verify that same artifact. When global OCI signature verification was enabled via `OCI_TRUST_POLICY` (`enabled: true`), an attacker with write access to the configured OCI tag could publish an unsigned or improperly signed artifact containing `.doco-cd.yml` with `oci.verify: false`. This could cause signature verification to be bypassed and untrusted deployment content to be applied. This primarily impacts users deploying from OCI artifacts where deployment config is read from artifact contents (for example, poll/webhook flows without trusted inline deployment overrides). The issue is fixed by enforcing a strict trust boundary and no-downgrade behavior. First, artifact-contained `.doco-cd.yml` is treated as untrusted for OCI trust-policy override decisions. Second, if global `OCI_TRUST_POLICY.enabled` is `true`, per-deployment `oci.verify: false` cannot disable verification. Some workarounds are available. Do not source deployment config from untrusted OCI artifact contents. Use trusted inline `POLL_CONFIG.deployments` and avoid relying on artifact-contained trust-policy overrides. Restrict write/push permissions for OCI repositories/tags used by doco-cd. Prefer immutable digest pinning and protected release/tag workflows. Monitor for unexpected artifact digest changes and failed/suspicious verification events.
CVE-2026-89086 Critical 2026-09-10 Not applicable Proof of concept only In the jose package before 0.11.0 for OCaml, library calls to validate an RSA signature only confirm that PKCS #1 decoding succeeds, and proceed to declare the signature valid without the required steps that involve the public key.
CVE-2026-89043 Critical 2026-09-10 Not applicable Proof of concept only passport-saml-encrypted through 0.1.13 contains an XML signature wrapping vulnerability where signature verification and assertion extraction use independent XPath lookups with no cross-validation. Attackers holding any validly signed SAML message can prepend a forged unsigned assertion that gets accepted as the verified identity while the genuine signature validates against the original assertion.
CVE-2026-89042 Critical 2026-09-10 Not applicable No public exploit passport-saml-encrypted through 0.1.13 makes SAML signature verification conditional on an optional cert option, allowing attackers to bypass authentication by submitting unsigned SAML responses. Attackers can post forged SAML responses with arbitrary NameID and attributes to the assertion consumer service endpoint to receive authenticated profiles without valid signatures.
CVE-2026-87732 Medium 2026-09-09 Not applicable Proof of concept only An issue was discovered in the mirage-crypto package before 2.2.0 for OCaml. The AES.GCM.authenticate_decrypt_into and Chacha20.authenticate_decrypt_into functions write the decrypted plaintext into a caller-provided buffer and only then compares the tag. On a forged tag, the functions returns false, but the destination buffer already holds the full plaintext.
CVE-2026-79970 Medium 2026-09-09 Not applicable No public exploit Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Improper Verification of Cryptographic Signature vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to protection mechanism bypass.
CVE-2026-56207 Critical 2026-09-09 Not applicable No public exploit Signature of Bearer token is not verified in last step of SAML2 authentication for Impala's hs2-http interface, allowing altering user name and acting as another user. This issue affects Apache Impala: >=4.0.0. Users are recommended to upgrade to version 4.5.2, which fixes this issue.
CVE-2023-54355 High 2026-09-09 Not applicable No public exploit PocketMine-MP versions before 5.3.1 and 4.23.1 fail to validate that the identityPublicKey in LoginPacket uses the required secp384r1 elliptic curve. Attackers can provide LoginPackets with keys using different curves or non-EC key types to pass login verification but trigger an uncaught exception during ECDH key derivation, crashing the server.
CVE-2026-86080 Medium 2026-09-08 Not applicable No public exploit n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the GitHub Trigger generated a webhook secret but discarded it when GitHub returned HTTP 422 and the node reused an existing webhook. Workflow static data then retained webhookId without webhookSecret, and X-Hub-Signature-256 verification accepted deliveries without a stored secret. The affected logic includes packages/nodes-base/nodes/Github/GithubTriggerHelpers.ts and the 422 webhook reuse path. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
CVE-2026-77105 High 2026-09-08 Not applicable No public exploit CommServe contained a cryptographic signature verification issue affecting privilege management. Software customers upgrade to resolved maintenance release. Update CommServe and Web Server.
CVE-2026-69646 High 2026-09-08 Not applicable No public exploit Improper verification of cryptographic signature in Skype for Business allows an unauthorized attacker to perform spoofing over an adjacent network.
CVE-2026-57098 High 2026-09-08 Not applicable No public exploit Improper verification of cryptographic signature in Windows RDP Client allows an unauthorized attacker to disclose information over a network.
CVE-2026-52486 Medium 2026-09-08 Not applicable Proof of concept only An issue in OpenDDS 3.33.x allows a local attacker to cause a denial of service via the verify function in the SIgnedDocument module
CVE-2026-28590 High 2026-09-08 Not applicable No public exploit In multiple locations, there is a possible improper encryption key validation due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
CVE-2026-14296 High 2026-09-07 Not applicable No public exploit When using the Direct XIP update strategy, the main application image starts other cores (i.e. radio core), based on the currently active slot without additional verification. The MCUboot in the bare (upstream) configuration assumes that if there is at least a single slot for each image available, the system is bootable and continues the boot process. This may lead to a situation when MCUboot picks different slot for different images (i.e. (a) for the main application and (b) for the radio image), boots the main application (from slot (a)) that afterwards starts the radio image by providing an address of the unauthenticated slot ((a) instead of (b)).
CVE-2026-86304 Critical 2026-09-06 Not applicable No public exploit MojoX::Authentication versions before 0.006 for Perl allow SAML authentication bypass because parse_assertion builds Net::SAML2::Binding::POST without a trust anchor. parse_assertion in MojoX::Authentication::Model::SAML2 calls Net::SAML2::Binding::POST->new with no cacert, cert_text or anchors argument, then passes the returned XML to Net::SAML2::Protocol::Assertion->new_from_xml with the IdP signing certificate as cacert. In Net::SAML2 before 0.86 that certificate guards only encrypted assertions, so the signature on an unencrypted assertion is checked against the certificate the response itself carries. An attacker starts a SAML login, then posts a response signed with a certificate of their own. The audience, InResponseTo and timestamp checks that follow are all satisfiable by the attacker, so the response authenticates any NameID it carries.
CVE-2026-67278 Medium 2026-09-05 Not applicable Proof of concept only MikroTik RouterOS accepts malformed RSA/PKCS#1 v1.5 signatures across RSA-based services, including TLS/X.509 certificate validation and SSH host-key authentication. Because its trust store includes an e=3 root CA, an attacker controlling or redirecting an outbound RouterOS TLS connection can use the root’s public certificate - without its private key - to forge a trusted intermediate and issue certificates for arbitrary hostnames, enabling TLS server impersonation. The same permissive verification also undermines RSA-based SSH authentication. This issue affects only 7.x branch was fixed in versions: 7.23.6 (Long-term) and 7.24.3 (Stable). Releases 7.23.4 and 7.24.2 included an incomplete fix.
CVE-2026-67276 Critical 2026-09-05 Not applicable Exploited RouterOS does not compare the complete RSA public key when matching an SSH authentication request to an authorized user key, checking the key type and modulus but omitting the exponent. Because signature verification uses the client-supplied key, an attacker knowing an authorized RSA modulus can supply a key with exponent one, forge a valid signature, and open an SSH command channel as the target user without the private key.This issue affects only 7.x branch was fixed in versions: 7.23.4 (Long-term) and 7.24.2 (Stable)
CVE-2026-52767 High 2026-09-05 Not applicable Proof of concept only YesWiki is a wiki system written in PHP. From version 4.6.2 to before version 4.6.6, HttpSignatureService::verifySignature() checks the result of PHP's openssl_verify() with a loose boolean negation - if (!openssl_verify(...)) { throw ... }. PHP's openssl_verify has four possible return values: 1, 0, -1, and "false". The -1 row is the bypass: PHP's truthiness rules make -1 a truthy value, so !(-1) === false, the throw is skipped, and the controller proceeds to processActivity(). Any condition that makes OpenSSL's EVP_VerifyFinal() return -1 triggers the bypass. The reachable consequence is the controller silently treats a failed verification as success and processes the attacker's payload. This issue has been patched in version 4.6.6.
CVE-2026-85525 High 2026-09-04 No exploit published No public exploit Improper OCSP response validation in the Snowflake Python, Go, JDBC, and Node.js drivers allowed a revoked TLS certificate to be accepted as valid, because OCSP responses were not reliably bound to the certificate being validated and definitive verification failures were treated as transient. A man-in-the-middle attacker holding a revoked certificate and its private key for a Snowflake or stage hostname could cause the driver to establish a TLS session to the attacker-controlled endpoint anyway, allowing the attacker to read and modify data transmitted within that connection. Successful exploitation requires that on-path position and the corresponding private key, and impact is limited to data carried within the intercepted connection. The fix is available in Snowflake Connector for Python v4.7.3, Snowflake Go Driver v2.2.0, Snowflake JDBC Driver v4.3.4 (including the snowflake-jdbc-fips and snowflake-jdbc-thin), and Snowflake Node.js Driver v3.3.0. Users must manually upgrade.
CVE-2026-79389 High 2026-09-04 Not applicable No public exploit Trueview T18161 S 6.0.23.4 contains an improper verification in MQTT command processing. An attacker with network access can replay or modify captured MQTT messages, including security-related nonce, timestamp, and signature fields, and the device accepts the modified messages and executes the associated commands.
CVE-2026-85394 Critical 2026-09-03 Not applicable No public exploit python-jose through 3.5.0 fails to properly validate asymmetric keys in HMAC initialization, accepting DER-encoded public keys that lack PEM armor or SSH prefixes. Attackers holding the service's public key can forge HS256 tokens that pass verification when algorithms are not explicitly restricted. This is an incomplete fix for CVE-2024-33663.
CVE-2026-85393 High 2026-09-03 Not applicable Proof of concept only node-forge through 1.4.0 fails to validate element count in nested DigestAlgorithm sequences during RSA PKCS#1 v1.5 signature verification. Attackers can embed garbage bytes inside the DigestAlgorithm sequence to forge valid signatures for arbitrary messages using low-exponent RSA keys. This is an incomplete fix for CVE-2026-33894.
CVE-2026-84185 Medium 2026-09-03 Not applicable No public exploit A flaw was found in the jwcrypto library, which is used for implementing Javascript Object Signing and Encryption (JOSE) standards. The issue occurs when the library verifies a General JSON Serialization JWS using a set of keys. Due to a coding error, the library fails to correctly identify the specific key ID (kid) and may instead accept a signature made by any valid key in the set. This can allow an attacker with a valid key to bypass authorization checks in applications that rely on the key ID to identify specific tenants or users.
CVE-2026-80465 High 2026-09-03 Not applicable No public exploit A vulnerability has been identified in Mendix SAML (Mendix 10 compatible) (All versions < V4.2.4), Mendix SAML (Mendix 11 compatible) (All versions < V4.2.4), Mendix SAML (Mendix 9.24 compatible) (All versions < V3.6.29). Affected versions of the module do not properly validate the SAML response signature. This could allow unauthenticated remote attackers to hijack an account (session) in specific SSO configurations.
CVE-2026-80098 Critical 2026-09-03 Not applicable No public exploit Improper verification of cryptographic signature in Copilot Studio allows an unauthorized attacker to elevate privileges over a network.
CVE-2026-82955 Critical 2026-09-02 Not applicable No public exploit In the current development version of Eclipse aeriOS, which has not yet had an official release, the KrakenD instance included in the API Gateway component had the disable_jwk_security parameter hard-coded to true, with no option to override it through the Helm chart configuration. This setting disables TLS certificate verification when KrakenD retrieves the JSON Web Key Set (JWKS) used to validate bearer tokens, potentially allowing an attacker with the ability to intercept this communication to provide a malicious JWKS and compromise token validation. The issue has been addressed by making the parameter configurable through the boolean Helm value krakend.config.disableJwkSecurity and setting its default value to false, ensuring that TLS certificate verification is enabled by default.
