{"id":"CVE-2026-25476","summary":"OpenEMR has Session Timeout Bypass via skip_timeout_reset","details":"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.","aliases":["GHSA-gx7q-6fhr-5h33"],"modified":"2026-08-12T03:51:29.872309537Z","published":"2026-02-25T18:28:29.881Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-613"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25476.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25476.json"},{"type":"ADVISORY","url":"https://github.com/openemr/openemr/security/advisories/GHSA-gx7q-6fhr-5h33"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25476"},{"type":"FIX","url":"https://github.com/openemr/openemr/commit/02a6a7793402b10356a94626d78e0e1069e92a77"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openemr/openemr","events":[{"introduced":"0"},{"fixed":"b91b73600327acb46252b9fce7d04467eea126fd"},{"fixed":"02a6a7793402b10356a94626d78e0e1069e92a77"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"8.0.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:open-emr:openemr:*:*:*:*:*:*:*:*"}}],"versions":["v3_0_1","v3_0_0","v2_9_0","v2_8_3","v2_8_2","v2_8_1","v2_8_0","v2_7_3-rc1","v2_7_2","v2_7_2-rc2","v2_7_2-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-25476.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
