CVE-2026-25476

OpenEMR is a free and open source electronic health records and medical practice management application.

Published Feb 25, 2026 · updated Jun 17, 2026 · open-emr openemr

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 runs only when is not present in the request. When is sent, the entire block that calls 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 to avoid being logged out. Version 8.0.0 fixes the issue.
