Description

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.
