An attacker could craft a token (for example a UsernameToken or a self-signed SAML Assertion) whose hash collides with a cached entry. The token would then be accepted without password validation, signature trust verification or a call to the STS. This could let the attacker authenticate as another user and, through STS token validation or renewal, obtain STS-signed tokens for that identity.\nUsers are recommended to upgrade to versions 4.2.4 or 4.1.9 or 3.6.13, which fix this issue.","state":0,"publishedAt":"2026-10-09T10:18:56.568+00:00","modifiedAt":"2026-10-15T16:28:54.151+00:00","affected":[{"ecosystem":"https://repo.maven.apache.org/maven2","name":"org.apache.cxf:cxf-rt-ws-security","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Apache Software Foundation\",\n                    \"product\": \"Apache CXF\",\n                    \"packageURL\": \"pkg:maven/org.apache.cxf/cxf-rt-ws-security\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.2.0\",\n                            \"lessThan\": \"4.2.4\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.0.0\",\n                            \"lessThan\": \"4.1.9\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThan\": \"3.6.13\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"collectionURL\": \"https://repo.maven.apache.org/maven2\",\n                    \"packageName\": \"org.apache.cxf:cxf-rt-ws-security\"\n                }"}],"metrics":[],"references":["https://lists.apache.org/thread.html/qthbnsyhqsxhl9p2h9v5dg4mnwv1b9r6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97468","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97468","identifiers":["CVE-2026-97468"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
