Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of openemr/openemr published their own advisory on GitHub. Reviewed sources take precedence over it.
