Summary
OpenEMR before 8.5.0 contains a cross-site request forgery vulnerability in ObservationController::deleteAction that allows attackers to delete observation form records without a CSRF token. Attackers can lure a logged-in clinician to a page issuing a GET to delete.php with guessed id values, soft-deleting observations in the victim's open encounter.

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.
