  "title": "UsernameToken nonce replay bypass in Apache WSS4J",
  "summary": "Apache WSS4J's DOM WS-Security package can fail to recognize a previously seen UsernameToken nonce when its encoding is represented differently. An attacker who has captured a valid password-digest UsernameToken may replay it to submit requests until the token expires; deployments need both password-digest tokens and a configured nonce replay cache to be affected.",
  "mitigation": "Upgrade org.apache.wss4j:wss4j-ws-security-dom to 4.0.2, 3.0.6, or 2.4.4, as appropriate for your release branch. Restrict exposure of captured authenticated requests until the upgrade is complete.",
