OpenEMR before 8.5.0 contains a missing authorization vulnerability that allows authenticated users lacking nationnotes/nn_configure to modify shared Nation Notes templates by calling mutation endpoints directly. Attackers can send requests to ajax_code.php or add_context.php, which lack ACL and CSRF checks, to tamper with clinical-note templates and assignments.
