CVE Severity Published▾ Status Exploitation Description
CVE-2026-3429 Medium 2026-03-11 No exploit published No public exploit A flaw was identified in the Account REST API of Keycloak that allows a user authenticated at a lower security level to perform sensitive actions intended only for higher-assurance sessions. Specifically, an attacker who has already obtained a victim’s password can delete the victim’s registered MFA/OTP credential without first proving possession of that factor. The attacker can then register their own MFA device, effectively taking full control of the account. This weakness undermines the intended protection provided by multi-factor authentication.
CVE-2026-3047 High 2026-03-05 No exploit published No public exploit A flaw was found in org.keycloak.broker.saml. When a disabled Security Assertion Markup Language (SAML) client is configured as an Identity Provider (IdP)-initiated broker landing target, it can still complete the login process and establish a Single Sign-On (SSO) session. This allows a remote attacker to gain unauthorized access to other enabled clients without re-authentication, effectively bypassing security restrictions.
CVE-2026-3009 High 2026-03-05 No exploit published No public exploit A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.
CVE-2026-0871 Medium 2026-02-27 No exploit published No public exploit A flaw was found in Keycloak. An administrator with `manage-users` permission can bypass the "Only administrators can view" setting for unmanaged attributes, allowing them to modify these attributes. This improper access control can lead to unauthorized changes to user profiles, even when the system is configured to restrict such modifications.
CVE-2025-12150 Low 2026-02-27 No exploit published No public exploit A flaw was found in Keycloak’s WebAuthn registration component. This vulnerability allows an attacker to bypass the configured attestation policy and register untrusted or forged authenticators via submission of an attestation object with fmt: "none", even when the realm is configured to require direct attestation. This can lead to weakened authentication integrity and unauthorized authenticator registration.
CVE-2025-12543 Critical 2026-01-07 No exploit published Proof of concept only A flaw was found in the Undertow HTTP server core, which is used in WildFly, JBoss EAP, and other Java applications. The Undertow library fails to properly validate the Host header in incoming HTTP requests.As a result, requests containing malformed or malicious Host headers are processed without rejection, enabling attackers to poison caches, perform internal network scans, or hijack user sessions.
CVE-2025-9784 High 2025-09-02 No exploit published No public exploit A flaw was found in Undertow where malformed client requests can trigger server-side stream resets without triggering abuse counters. This issue, referred to as the "MadeYouReset" attack, allows malicious clients to induce excessive server workload by repeatedly causing server-side stream aborts. While not a protocol bug, this highlights a common implementation weakness that can be exploited to cause a denial of service (DoS).
CVE-2025-8419 Medium 2025-08-06 No exploit published No public exploit A vulnerability was found in Keycloak-services. Special characters used during e-mail registration may perform SMTP Injection and unexpectedly send short unwanted e-mails. The email is limited to 64 characters (limited local part of the email), so the attack is limited to very shorts emails (subject and little data, the example is 60 chars). This flaw's only direct consequence is an unsolicited email being sent from the Keycloak server. However, this action could be a precursor for more sophisticated attacks.
CVE-2025-7784 Medium 2025-07-18 No exploit published No public exploit A flaw was found in the Keycloak identity and access management system when Fine-Grained Admin Permissions(FGAPv2) are enabled. An administrative user with the manage-users role can escalate their privileges to realm-admin due to improper privilege enforcement. This vulnerability allows unauthorized elevation of access rights, compromising the intended separation of administrative duties and posing a security risk to the realm.
CVE-2025-7365 High 2025-07-10 No exploit published No public exploit A flaw was found in Keycloak. When an authenticated attacker attempts to merge accounts with another existing account during an identity provider (IdP) login, the attacker will subsequently be prompted to "review profile" information. This vulnerability allows the attacker to modify their email address to match that of a victim's account, triggering a verification email sent to the victim's email address. The attacker's email address is not present in the verification email content, making it a potential phishing opportunity. If the victim clicks the verification link, the attacker can gain access to the victim's account.
CVE-2025-5731 Medium 2025-06-26 No exploit published No public exploit A flaw was found in Infinispan CLI. A sensitive password, decoded from a Base64-encoded Kubernetes secret, is processed in plaintext and included in a command string that may expose the data in an error message when a command is not found.
CVE-2025-5416 Low 2025-06-20 No exploit published No public exploit A vulnerability has been identified in Keycloak that could lead to unauthorized information disclosure. While it requires an already authenticated user, the /admin/serverinfo endpoint can inadvertently provide sensitive environment information.
CVE-2025-35036 Medium 2025-06-03 No exploit published Proof of concept only Hibernate Validator before 6.2.0 and 7.0.0, by default and depending how it is used, may interpolate user-supplied input in a constraint violation message with Expression Language. This could allow an attacker to access sensitive information or execute arbitrary Java code. Hibernate Validator as of 6.2.0 and 7.0.0 no longer interpolates custom constraint violation messages with Expression Language and strongly recommends not allowing user-supplied input in constraint violation messages. CVE-2020-5245 and CVE-2025-4428 are examples of related, downstream vulnerabilities involving Expression Language intepolation of user-supplied data.
CVE-2025-3910 Medium 2025-04-29 No exploit published No public exploit A flaw was found in Keycloak. The org.keycloak.authorization package may be vulnerable to circumventing required actions, allowing users to circumvent requirements such as setting up two-factor authentication.
CVE-2025-23368 High 2025-03-04 No exploit published No public exploit A flaw was found in Wildfly Elytron integration. The component does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks via CLI.
CVE-2025-23367 Medium 2025-01-30 No exploit published No public exploit A flaw was found in the Wildfly Server Role Based Access Control (RBAC) provider. When authorization to control management operations is secured using the Role Based Access Control provider, a user without the required privileges can suspend or resume the server. A user with a Monitor or Auditor role is supposed to have only read access permissions and should not be able to suspend the server. The vulnerability is caused by the Suspend and Resume handlers not performing authorization checks to validate whether the current user has the required permissions to proceed with the action.
CVE-2025-23366 Medium 2025-01-14 No exploit published No public exploit A flaw was found in the HAL Console in the Wildfly component, which does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output used as a web page that is served to other users. The attacker must be authenticated as a user that belongs to management groups “SuperUser”, “Admin”, or “Maintainer”.
CVE-2023-1932 Medium 2024-11-07 No exploit published No public exploit A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.
CVE-2024-51127 Critical 2024-11-04 No exploit published No public exploit An issue in the createTempFile method of hornetq v2.4.9 allows attackers to arbitrarily overwrite files or access sensitive information.
CVE-2024-10234 High 2024-10-22 No exploit published No public exploit A vulnerability was found in Wildfly, where a user may perform Cross-site scripting in the Wildfly deployment system. This flaw allows an attacker or insider to execute a deployment with a malicious payload, which could trigger undesired behavior against the server.
CVE-2023-6841 High 2024-09-10 No exploit published No public exploit A denial of service vulnerability was found in keycloak where the amount of attributes per object is not limited,an attacker by sending repeated HTTP requests could cause a resource exhaustion when the application send back rows with long attribute values.
CVE-2024-7341 High 2024-09-09 No exploit published No public exploit A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2024-7318 Medium 2024-09-09 No exploit published No public exploit A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.
CVE-2024-7260 Medium 2024-09-09 No exploit published No public exploit An open redirect vulnerability was found in Keycloak. A specially crafted URL can be constructed where the referrer and referrer_uri parameters are made to trick a user to visit a malicious webpage. A trusted URL can trick users and automation into believing that the URL is safe, when, in fact, it redirects to a malicious server. This issue can result in a victim inadvertently trusting the destination of the redirect, potentially leading to a successful phishing attack or other types of attacks. Once a crafted URL is made, it can be sent to a Keycloak admin via email for example. This will trigger this vulnerability when the user visits the page and clicks the link. A malicious actor can use this to target users they know are Keycloak admins for further attacks. It may also be possible to bypass other domain-related security checks, such as supplying this as a OAuth redirect uri. The malicious actor can further obfuscate the redirect_uri using URL encoding, to hide the text of the actual malicious website domain.
CVE-2024-4629 Medium 2024-09-03 No exploit published No public exploit A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.
CVE-2024-8285 Medium 2024-08-30 No exploit published No public exploit A flaw was found in Kroxylicious. When establishing the connection with the upstream Kafka server using a TLS secured connection, Kroxylicious fails to properly verify the server's hostname, resulting in an insecure connection. For a successful attack to be performed, the attacker needs to perform a Man-in-the-Middle attack or compromise any external systems, such as DNS or network routing configuration. This issue is considered a high complexity attack, with additional high privileges required, as the attack would need access to the Kroxylicious configuration or a peer system. The result of a successful attack impacts both data integrity and confidentiality.
CVE-2024-7885 High 2024-08-21 No exploit published No public exploit A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
CVE-2024-1102 Medium 2024-04-25 No exploit published No public exploit A vulnerability was found in jberet-core logging. An exception in 'dbProperties' might display user credentials such as the username and password for the database-connection.
CVE-2023-6787 High 2024-04-25 No exploit published No public exploit A flaw was found in Keycloak that occurs from an error in the re-authentication mechanism within org.keycloak.authentication. This flaw allows hijacking an active Keycloak session by triggering a new authentication process with the query parameter "prompt=login," prompting the user to re-enter their credentials. If the user cancels this re-authentication by selecting "Restart login," an account takeover may occur, as the new session, with a different SUB, will possess the same SID as the previous session.
CVE-2024-1722 Medium 2024-02-29 No exploit published No public exploit A flaw was found in Keycloak. In certain conditions, this issue may allow a remote unauthenticated attacker to block other accounts from logging in.
CVE-2024-1635 High 2024-02-19 No exploit published No public exploit A vulnerability was found in Undertow. This vulnerability impacts a server that supports the wildfly-http-client protocol. Whenever a malicious user opens and closes a connection with the HTTP port of the server and then closes the connection immediately, the server will end with both memory and open file limits exhausted at some point, depending on the amount of memory available. At HTTP upgrade to remoting, the WriteTimeoutStreamSinkConduit leaks connections if RemotingConnection is closed by Remoting ServerConnectionOpenListener. Because the remoting connection originates in Undertow as part of the HTTP upgrade, there is an external layer to the remoting connection. This connection is unaware of the outermost layer when closing the connection during the connection opening procedure. Hence, the Undertow WriteTimeoutStreamSinkConduit is not notified of the closed connection in this scenario. Because WriteTimeoutStreamSinkConduit creates a timeout task, the whole dependency tree leaks via that task, which is added to XNIO WorkerThread. So, the workerThread points to the Undertow conduit, which contains the connections and causes the leak.
CVE-2023-4503 High 2024-02-06 No exploit published No public exploit An improper initialization vulnerability was found in Galleon. When using Galleon to provision custom EAP or EAP-XP servers, the servers are created unsecured. This issue could allow an attacker to access remote HTTP services available from the server.
CVE-2023-6291 High 2024-01-26 No exploit published No public exploit A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users.
CVE-2023-2585 High 2023-12-21 No exploit published No public exploit Keycloak's device authorization grant does not correctly validate the device code and client ID. An attacker client could abuse the missing validation to spoof a client consent request and trick an authorization admin into granting consent to a malicious OAuth client or possible unauthorized access to an existing OAuth client.
CVE-2023-6927 Medium 2023-12-18 No exploit published No public exploit A flaw was found in Keycloak. This issue may allow an attacker to steal authorization codes or tokens from clients using a wildcard in the JARM response mode "form_post.jwt" which could be used to bypass the security patch implemented to address CVE-2023-6134.
CVE-2023-5384 High 2023-12-18 No exploit published No public exploit A flaw was found in Infinispan. When serializing the configuration for a cache to XML/JSON/YAML, which contains credentials (JDBC store with connection pooling, remote store), the credentials are returned in clear text as part of the configuration.
CVE-2023-5236 Medium 2023-12-18 No exploit published No public exploit A flaw was found in Infinispan, which does not detect circular object references when unmarshalling. An authenticated attacker with sufficient permissions could insert a maliciously constructed object into the cache and use it to cause out of memory errors and achieve a denial of service.
CVE-2023-3629 Medium 2023-12-18 No exploit published No public exploit A flaw was found in Infinispan's REST, Cache retrieval endpoints do not properly evaluate the necessary admin permissions for the operation. This issue could allow an authenticated user to access information outside of their intended permissions.
CVE-2023-3628 Medium 2023-12-18 No exploit published No public exploit A flaw was found in Infinispan's REST. Bulk read endpoints do not properly evaluate user permissions for the operation. This issue could allow an authenticated user to access information outside of their intended permissions.
CVE-2023-6563 High 2023-12-14 No exploit published No public exploit An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system.
CVE-2023-6134 Medium 2023-12-14 No exploit published No public exploit A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.
CVE-2023-5379 High 2023-12-12 No exploit published No public exploit A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS).
CVE-2023-6394 Critical 2023-12-09 No exploit published No public exploit A flaw was found in Quarkus. This issue occurs when receiving a request over websocket with no role-based permission specified on the GraphQL operation, Quarkus processes the request without authentication despite the endpoint being secured. This can allow an attacker to access information and functionality outside of normal granted API permissions.
CVE-2023-6393 Medium 2023-12-06 No exploit published No public exploit A flaw was found in the Quarkus Cache Runtime. When request processing utilizes a Uni cached using @CacheResult and the cached Uni reuses the initial "completion" context, the processing switches to the cached Uni instead of the request context. This is a problem if the cached Uni context contains sensitive information, and could allow a malicious user to benefit from a POST request returning the response that is meant for another user, gaining access to sensitive data.
CVE-2023-4061 Medium 2023-11-08 No exploit published No public exploit A flaw was found in wildfly-core. A management user could use the resolve-expression in the HAL Interface to read possible sensitive information from the Wildfly system. This issue could allow a malicious user to access the system and obtain possible sensitive information from the system.
CVE-2023-4586 High 2023-10-04 No exploit published No public exploit A vulnerability was found in the Hot Rod client. This security issue occurs as the Hot Rod client does not enable hostname validation when using TLS, possibly resulting in a man-in-the-middle (MITM) attack.
CVE-2023-2422 High 2023-10-04 No exploit published No public exploit A flaw was found in Keycloak. A Keycloak server configured to support mTLS authentication for OAuth/OpenID clients does not properly verify the client certificate chain. A client that possesses a proper certificate can authorize itself as any other client, therefore, access data that belongs to other clients.
CVE-2023-4066 Medium 2023-09-27 No exploit published No public exploit A flaw was found in Red Hat's AMQ Broker, which stores certain passwords in a secret security-properties-prop-module, defined in ActivemqArtemisSecurity CR; however, they are shown in plaintext in the StatefulSet details yaml of AMQ Broker.
CVE-2023-4065 Medium 2023-09-27 No exploit published No public exploit A flaw was found in Red Hat AMQ Broker Operator, where it displayed a password defined in ActiveMQArtemisAddress CR, shown in plain text in the Operator Log. This flaw allows an authenticated local attacker to access information outside of their permissions.
CVE-2023-3223 High 2023-09-27 No exploit published No public exploit A flaw was found in undertow. Servlets annotated with @MultipartConfig may cause an OutOfMemoryError due to large multipart content. This may allow unauthorized users to cause remote Denial of Service (DoS) attack. If the server uses fileSizeThreshold to limit the file size, it's possible to bypass the limit by setting the file name in the request to null.
CVE-2023-0833 Medium 2023-09-27 No exploit published No public exploit A flaw was found in Red Hat's AMQ-Streams, which ships a version of the OKHttp component with an information disclosure flaw via an exception triggered by a header containing an illegal value. This issue could allow an authenticated attacker to access information outside of their regular permissions.
CVE-2022-4137 High 2023-09-25 No exploit published No public exploit A reflected cross-site scripting (XSS) vulnerability was found in the 'oob' OAuth endpoint due to incorrect null-byte handling. This issue allows a malicious link to insert an arbitrary URI into a Keycloak error page. This flaw requires a user or administrator to interact with a link in order to be vulnerable. This may compromise user details, allowing it to be changed or collected by an attacker.
CVE-2022-4039 Critical 2023-09-22 No exploit published No public exploit A flaw was found in Red Hat Single Sign-On for OpenShift container images, which are configured with an unsecured management interface enabled. This flaw allows an attacker to use this interface to deploy malicious code and access and modify potentially sensitive information in the app server configuration.
CVE-2023-4853 High 2023-09-20 No exploit published No public exploit A flaw was found in Quarkus where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a denial of service.
CVE-2022-3916 Medium 2023-09-20 No exploit published No public exploit A flaw was found in the offline_access scope in Keycloak. This issue would affect users of shared computers more (especially if cookies are not cleared), due to a lack of root session validation, and the reuse of session ids across root and user authentication sessions. This enables an attacker to resolve a user session attached to a previously authenticated user; when utilizing the refresh token, they will be issued a token for the original user.
CVE-2022-1438 Medium 2023-09-20 No exploit published No public exploit A flaw was found in Keycloak. Under specific circumstances, HTML entities are not sanitized during user impersonation, resulting in a Cross-site scripting (XSS) vulnerability.
CVE-2023-1108 High 2023-09-14 No exploit published No public exploit A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.
CVE-2023-4918 High 2023-09-12 No exploit published No public exploit A flaw was found in the Keycloak package, more specifically org.keycloak.userprofile. When a user registers itself through registration flow, the "password" and "password-confirm" field from the form will occur as regular user attributes. All users and clients with proper rights and roles are able to read users attributes, allowing a malicious user with minimal access to retrieve the users passwords in clear text, jeopardizing their environment.
CVE-2023-2974 High 2023-07-04 No exploit published No public exploit A vulnerability was found in quarkus-core. This vulnerability occurs because the TLS protocol configured with quarkus.http.ssl.protocols is not enforced, and the client can force the selection of the weaker supported TLS protocol.
CVE-2023-1664 Medium 2023-05-26 No exploit published No public exploit A flaw was found in Keycloak. This flaw depends on a non-default configuration "Revalidate Client Certificate" to be enabled and the reverse proxy is not validating the certificate before Keycloak. Using this method an attacker may choose the certificate which will be validated by the server. If this happens and the KC_SPI_TRUSTSTORE_FILE_FILE variable is missing/misconfigured, any trustfile may be accepted with the logging information of "Cannot validate client certificate trust: Truststore not available". This may not impact availability as the attacker would have no access to the server, but consumer applications Integrity or Confidentiality may be impacted considering a possible access to them. Considering the environment is correctly set to use "Revalidate Client Certificate" this flaw is avoidable.
CVE-2022-1274 Medium 2023-03-29 No exploit published No public exploit A flaw was found in Keycloak in the execute-actions-email endpoint. This issue allows arbitrary HTML to be injected into emails sent to Keycloak users and can be misused to perform phishing or other attacks against users.
CVE-2023-0044 Medium 2023-02-23 No exploit published No public exploit If the Quarkus Form Authentication session cookie Path attribute is set to `/` then a cross-site attack may be initiated which might lead to the Information Disclosure. This attack can be prevented with the Quarkus CSRF Prevention feature.
CVE-2022-4492 High 2023-02-23 No exploit published No public exploit The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.
CVE-2023-0482 Medium 2023-02-17 No exploit published No public exploit In RESTEasy the insecure File.createTempFile() is used in the DataSourceProvider, FileProvider and Mime4JWorkaround classes which creates temp files with insecure permissions that could be read by a local user.
CVE-2023-0105 Medium 2023-01-13 No exploit published No public exploit A flaw was found in Keycloak. This flaw allows impersonation and lockout due to the email trust not being handled correctly in Keycloak. An attacker can shadow other users with the same email and lockout or impersonate them.
CVE-2023-0091 Low 2023-01-13 No exploit published No public exploit A flaw was found in Keycloak, where it did not properly check client tokens for possible revocation in its client credential flow. This flaw allows an attacker to access or modify potentially sensitive information.
CVE-2022-3143 High 2023-01-13 No exploit published No public exploit wildfly-elytron: possible timing attacks via use of unsafe comparator. A flaw was found in Wildfly-elytron.

CVE-2022-2053 High 2022-08-05 No exploit published No public exploit When a POST request comes through AJP and the request exceeds the max-post-size limit (maxEntitySize), Undertow's AjpServerRequestConduit implementation closes a connection without sending any response to the client/proxy. This behavior results in that a front-end proxy marking the backend worker (application server) as an error state and not forward requests to the worker for a while. In mod_cluster, this continues until the next STATUS request (10 seconds intervals) from the application server updates the server state. So, in the worst case, it can result in "All workers are in error state" and mod_cluster responds "503 Service Unavailable" for a while (up to 10 seconds). In mod_proxy_balancer, it does not forward requests to the worker until the "retry" timeout passes. However, luckily, mod_proxy_balancer has "forcerecovery" setting (On by default; this parameter can force the immediate recovery of all workers without considering the retry parameter of the workers if all workers of a balancer are in error state.). So, unlike mod_cluster, mod_proxy_balancer does not result in responding "503 Service Unavailable". An attacker could use this behavior to send a malicious request and trigger server errors, resulting in DoS (denial of service). This flaw was fixed in Undertow 2.2.19.Final, Undertow 2.3.0.Alpha2.

CVE-2022-0866 Medium 2022-05-10 No exploit published No public exploit This is a concurrency issue that can result in the wrong caller principal being returned from the session context of an EJB that is configured with a RunAs principal. In particular, the org.jboss.as.ejb3.component.EJBComponent class has an incomingRunAsIdentity field. This field is used by the org.jboss.as.ejb3.security.RunAsPrincipalInterceptor to keep track of the current identity prior to switching to a new identity created using the RunAs principal. The exploit consist that the EJBComponent#incomingRunAsIdentity field is currently just a SecurityIdentity. This means in a concurrent environment, where multiple users are repeatedly invoking an EJB that is configured with a RunAs principal, it's possible for the wrong the caller principal to be returned from EJBComponent#getCallerPrincipal. Similarly, it's also possible for EJBComponent#isCallerInRole to return the wrong value. Both of these methods rely on incomingRunAsIdentity. Affects all versions of JBoss EAP from 7.1.0 and all versions of WildFly 11+ when Elytron is enabled.
