Description
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.
Affected configurations
• apache wss4j (< 2.4.4)
• apache wss4j (>= 3.0.0 < 3.0.6)
• apache wss4j (>= 4.0.0 < 4.0.2)
