{"schemaVersion":3,"id":"CVE-2026-97468","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Apache CXF's STSTokenValidator and Security Token Service (STS) cached validated security tokens under a non-cryptographic 32-bit hash of the token (Java Arrays.hashCode/hashCode()), and treated a cache hit as proof that the presented token had already been validated. 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.","dates":{"published":"2026-10-09T10:18:56.568Z","modified":"2026-10-15T16:28:54.151Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.1,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.1,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.1,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00187,"percentile":0.07796,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-10T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00187,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00187,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00187,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00187,"percentile":0.07796}],"last30":[{"date":"2026-10-10T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00173,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00187,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00187,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00187,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00187,"percentile":0.07796}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-328","name":"Use
