{"id":"CVE-2025-65954","summary":"SimpleSAMLphp-casserver  has an Open Redirect vulnerability via logout","details":"SimpleSAMLphp-casserver is a CAS 1.0 and 2.0 compliant CAS server in the form of a SimpleSAMLphp module. In versions below 6.3.1 and 7.0.0, the logout endpoint accepts a url query parameter to redirect to. casserver treats that url as trusted, and either (depending on configuration) redirects the browser there, or shows a \"you've been logged out\" page with a link to continue to that url. Impacted configs include 'enable_logout' =\u003e true, and 'skip_logout_page' -\u003e true. This issue has been resolved in versions 6.3.1 and 7.0.0.","aliases":["GHSA-cvrm-5hp6-h523"],"modified":"2026-08-12T03:51:19.612333656Z","published":"2026-05-18T19:57:07.228Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/65xxx/CVE-2025-65954.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-601"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/65xxx/CVE-2025-65954.json"},{"type":"ADVISORY","url":"https://github.com/simplesamlphp/simplesamlphp-module-casserver/security/advisories/GHSA-cvrm-5hp6-h523"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-65954"},{"type":"FIX","url":"https://github.com/simplesamlphp/simplesamlphp-module-casserver/commit/0462f50f00b3bb300d83067d11b74146a57bb8e0"},{"type":"FIX","url":"https://github.com/simplesamlphp/simplesamlphp-module-casserver/commit/fb6c6f1c7b9e757c93c5c306e1d36405e64f6dc5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/simplesamlphp/simplesamlphp-module-casserver","events":[{"introduced":"0"},{"fixed":"0462f50f00b3bb300d83067d11b74146a57bb8e0"},{"introduced":"207e0a03c44b02bfc11f5e9cb6f2aaf960e242af"},{"fixed":"fb6c6f1c7b9e757c93c5c306e1d36405e64f6dc5"}],"database_specific":{"source":["CPE_RANGE","CPE_STRING","REFERENCES"],"cpe":["cpe:2.3:a:simplesamlphp:simplesamlphp-module-casserver:*:*:*:*:*:*:*:*","cpe:2.3:a:simplesamlphp:simplesamlphp-module-casserver:7.0.0:rc1:*:*:*:*:*:*","cpe:2.3:a:simplesamlphp:simplesamlphp-module-casserver:7.0.0:rc2:*:*:*:*:*:*"],"extracted_events":[{"introduced":"0"},{"fixed":"6.3.1"},{"introduced":"7.0.0-rc1"},{"last_affected":"7.0.0-rc1"},{"introduced":"7.0.0-rc2"},{"last_affected":"7.0.0-rc2"}]}}],"versions":["7.0.0-rc1","7.0.0-rc2","v7.0.0-rc2","v6.3.0","v7.0.0-rc3","v7.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-65954.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N"}]}
