CVE Severity Published▾ Status Exploitation Description
CVE-2026-95616 High 2026-09-30 No exploit published No public exploit An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation. An unauthenticated attacker can send a SOAP message carrying an X.509 certificate whose SubjectKeyIdentifier extension declares a length of 0x7FFFFFFF; WSS4J decodes this while resolving the signature's key reference, before the message is authenticated, so an eleven-byte extension triggers a 2 GB allocation. Repeated requests exhaust server memory. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
CVE-2026-92899 Medium 2026-09-30 No exploit published No public exploit Apache WSS4J remembers the Nonce of each UsernameToken it accepts, so a captured token cannot be reused. It stored the Nonce as raw base64 text, but authentication decodes that text and uses the bytes.The same bytes can be written as base64 in several ways. An attacker who captured an authenticated request could re-send it with a space added to the Nonce: the password digest still verified, but the token no longer matched the remembered one, so the replay was accepted. Since a UsernameToken does not cover the message body, the captured token could then be reused on requests of the attacker's choosing until it expired. Affects deployments with a nonce replay cache configured, as Apache CXF has by default, and only tokens using a password digest. The cache is now keyed on the decoded Nonce. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
CVE-2026-92121 High 2026-09-30 No exploit published No public exploit In the WSS4J streaming (StAX) code, a signature reference using the WS-Security STR-Transform leaves an internal "inside signed content" flag permanently set. The WS-SecurityPolicy enforcer uses that flag to decide whether an element needs checking, so it stops evaluating SignedParts and SignedElements for the rest of the message. A policy requiring the SOAP Body to be signed is then satisfied even when the Body carries no signature, removing the protection against XML Signature Wrapping. Signature verification itself is unaffected. The DOM code is not affected.  Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4 which fix this issue.
CVE-2026-89238 Critical 2026-09-30 No exploit published No public exploit WSS4J EncryptedHeader child confusion could promote an attacker-controlled plaintext element as the decrypted header, leading to incorrect confidentiality coverage and possible policy bypass. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
CVE-2026-88920 Critical 2026-09-30 No exploit published No public exploit An authentication bypass in the DOM security processor in Apache WSS4J allows unauthenticated remote attackers to forge authenticated SOAP messages via a crafted unsigned SAML sender-vouches assertion containing an attacker-controlled key. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
CVE-2026-87830 Critical 2026-09-30 No exploit published No public exploit In the StAX streaming WS-SecurityPolicy validator, certain relative or unsupported XPath expressions can be converted into paths that never match the actual XML element path. A remote SOAP peer may therefore send a required element without the expected signature or encryption. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
CVE-2026-85532 High 2026-09-30 No exploit published No public exploit Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum key length of 16 bytes, a maximum length of 512 bytes, and a maximum offset of 4096 bytes. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4, which fix this issue.
CVE-2020-13936 High 2021-03-10 No exploit published No public exploit An attacker that is able to modify Velocity templates may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. This applies to applications that allow untrusted users to upload/modify velocity templates running Apache Velocity Engine versions up to 2.2.
CVE-2011-2487 Medium 2020-03-11 Protected by Waratek No public exploit The implementations of PKCS#1 v1.5 key transport mechanism for XMLEncryption in JBossWS and Apache WSS4J before 1.6.5 is susceptible to a Bleichenbacher attack.
CVE-2015-0226 High 2017-10-30 Protected by Waratek No public exploit Apache WSS4J before 1.6.17 and 2.0.x before 2.0.2 improperly leaks information about decryption failures when decrypting an encrypted key or message data, which makes it easier for remote attackers to recover the plaintext form of a symmetric key via a series of crafted messages. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-2487.
CVE-2015-0227 Medium 2015-02-12 No exploit published No public exploit Apache WSS4J before 1.6.17 and 2.x before 2.0.2 allows remote attackers to bypass the requireSignedEncryptedDataElements configuration via a vectors related to "wrapping attacks."
CVE-2014-3623 Medium 2014-10-30 No exploit published No public exploit Apache WSS4J before 1.6.17 and 2.x before 2.0.2, as used in Apache CXF 2.7.x before 2.7.13 and 3.0.x before 3.0.2, when using TransportBinding, does not properly enforce the SAML SubjectConfirmation method security semantics, which allows remote attackers to conduct spoofing attacks via unspecified vectors.
