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...

EUVD-2026-89795

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-2026-88920 Apache WSS4J: SAML Sender-Vouches Authentication Bypass

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-2026-88920

A flaw in the DOM security processor of Apache WSS4J allows unauthenticated remote attackers to perform an authentication bypass . By submitting a crafted, unsigned SAML sender-vouches assertion containing an attacker-controlled key, an attacker can forge authenticated SOAP messages . To mitigate...

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...

CVE-2026-87830
