The WS-SecurityPolicy enforcer uses that flag to decide whether an element needs checking, so it stops evaluating SignedParts and SignedElements for the rest of the message. A policy requiring the SOAP Body to be signed is then satisfied even when the Body carries no signature, removing the protection against XML Signature Wrapping. Signature verification itself is unaffected. The DOM code is not affected.\u00A0\nUsers are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.4 which fix this issue.","state":0,"publishedAt":"2026-09-30T12:01:55.697+00:00","modifiedAt":"2026-09-30T19:51:55.272+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.wss4j:wss4j-ws-security-stax","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache WSS4J\",\n                    \"packageURL\": \"pkg:maven/org.apache.wss4j/wss4j-ws-security-stax\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.0.0\",\n                            \"lessThan\": \"4.0.2\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"3.0.0\",\n                            \"lessThan\": \"3.0.6\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"2.4.4\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.wss4j:wss4j-ws-security-stax\"\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread.html/oop9p4hpl5o9byosb1qg3z7q1sgnn4pc"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92121","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92121","identifiers":["CVE-2026-92121"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
