CVE-2026-88920

A flaw was found in Apache WSS4J. This vulnerability in the Document Object Model DOM security processor allows an unauthenticated remote attacker to bypass authentication and forge authenticated Simple Object Access Protocol SOAP messages. An attacker can exploit this issue by submitting a...

CVE-2026-92899

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 authenticat...

CVE-2026-95616 Apache WSS4J: Unauthenticated denial of service via integer overflow in DER parsing of X.509 certificate extensions

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...

CVE-2026-95616

Apache WSS4J is vulnerable to an integer overflow in its DER bounds check, which allows an oversized allocation to bypass validation. An unauthenticated attacker can exploit this by sending a SOAP message containing an X.509 certificate where the SubjectKeyIdentifier extension declares a length o...

CVE-2026-88920

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...

CVE-2026-85532

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 leng...

CVE-2026-92899 Apache WSS4J: UsernameToken replay protection bypassed by re-encoding the Nonce

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 authenticat...

CVE-2026-92899

The Apache WSS4J library is vulnerable to a replay protection bypass because it stores the Nonce of a UsernameToken as raw base64 text. While authentication uses the decoded bytes, an attacker can re-send a captured request with a space added to the base64 Nonce; the password digest remains valid...

CVE-2026-92121

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...

CVE-2026-92121 Apache WSS4J: WS-SecurityPolicy signature checks skipped in the streaming code after an STR-Transform reference

CVE-2026-89238 Apache WSS4J: WSS4J EncryptedHeader child confusion causing wrong protected-header selection

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-2026-87830 Apache WSS4J: Streaming WS-SecurityPolicy validation may skip element-protection checks.

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 recommend...
