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."}, {"lang": "es", "value": "OpenEMR es una aplicaci\u00f3n de gesti\u00f3n de registros de salud electr\u00f3nicos y pr\u00e1ctica m\u00e9dica de c\u00f3digo abierto y gratuita. Antes de la versi\u00f3n 8.0.0, la verificaci\u00f3n de expiraci\u00f3n de la sesi\u00f3n en `library/auth.inc.php` se ejecuta solo cuando `skip_timeout_reset` no est\u00e1 presente en la solicitud. Cuando se env\u00eda `skip_timeout_reset=1`, se omite todo el bloque que llama a `SessionTracker::isSessionExpired()` y fuerza el cierre de sesi\u00f3n por tiempo de espera.

La versi\u00f3n 8.0.0 soluciona el problema."}], "lastModified": "2026-06-17T10:24:41.983", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:open-emr:openemr:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FEAA9896-A42E-437C-BEE8-8DA955E34385", "versionEndExcluding": "8.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
