CVE-2026-126427
OpenEMR before 8.5.0 Idle Session Timeout Bypass via Eye Exam Form
OpenEMR before 8.5.0 contains a session expiration vulnerability that prevents automatic logoff because the Eye Exam form's read-only poll omits skip_timeout_reset. Attackers with physical access to an unattended workstation can use the still-active session to view patient health information, since update_READONLY() resets the idle timer every 15 seconds.
