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.
