Vulnerabilities

An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation.

Apache WSS4J remembers the Nonce of each UsernameToken it accepts, so a captured token cannot be reused.

In the WSS4J streaming (StAX) code, a signature reference using the WS-Security STR-Transform leaves an internal "inside signed content" flag permanently set.

WSS4J EncryptedHeader child confusion could promote an attacker-controlled plaintext element as the decrypted header, leading to incorrect confidentiality coverage and possible policy 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 attac…

Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds.
