{"id":"CVE-2026-25476","state":"PUBLISHED","title":"OpenEMR has Session Timeout Bypass via skip_timeout_reset","description":"OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the session expiration check in `library/auth.inc.php` runs only when `skip_timeout_reset` is not present in the request. When `skip_timeout_reset=1` is sent, the entire block that calls `SessionTracker::isSessionExpired()` and forces logout on timeout is skipped. As a result, any request that includes this parameter (e.g. from auto-refresh pages like the Patient Flow Board) never runs the expiration check: expired sessions can continue to access data indefinitely, abandoned workstations stay active, and an attacker with a stolen session cookie can keep sending `skip_timeout_reset=1` to avoid being logged out. Version 8.0.0 fixes the issue.","publishedAt":"2026-02-25T18:28:29.881Z","updatedAt":"2026-02-26T16:04:10.627Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["openemr openemr"],"affected":[{"vendor":"openemr","product":"openemr","versions":[{"version":"< 8.0.0","status":"affected"}]}],"references":["https://github.com/openemr/openemr/security/advisories/GHSA-gx7q-6fhr-5h33","https://github.com/openemr/openemr/commit/02a6a7793402b10356a94626d78e0e1069e92a77"],"weaknesses":["CWE-613"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/25xxx/CVE-2026-25476.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-25476","state":"PUBLISHED","datePublished":"2026-02-25T18:28:29.881Z","dateUpdated":"2026-02-26T16:04:10.627Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-02-02T16:31:35.820Z"},"containers":{"cna":{"title":"OpenEMR has Session Timeout Bypass via skip_timeout_reset","descriptions":[{"lang":"en","value":"OpenEMR is a free and open source electronic health records and medical practice management application.
