{"id":"CVE-2025-65954","aliases":["GHSA-cvrm-5hp6-h523"],"url":"https://o3.security/vulnerability/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' => true, and 'skip_logout_page' -> true. This issue has been resolved in versions 6.3.1 and 7.0.0.","published":"2026-05-18T19:57:07.228Z","modified":"2026-08-12T03:51:19.612333656Z","cvss":{"score":4.7,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N"},"epss":{"score":0.00269,"percentile":0.18946,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"simplesamlphp/simplesamlphp-module-casserver","fixedVersion":"7.0.0"},{"ecosystem":"Packagist","name":"simplesamlphp/simplesamlphp-module-casserver","fixedVersion":"6.3.1"}],"fix":{"url":"https://github.com/simplesamlphp/simplesamlphp-module-casserver/commit/0462f50f00b3bb300d83067d11b74146a57bb8e0","label":"simplesamlphp/simplesamlphp-module-casserver@0462f50"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:19.612333656Z"}}
