Description
OpenEMR before 8.5.0 contains a missing authorization vulnerability in the esign_form_submit handler of library/ESign/Form/Controller.php that verifies only the caller's password, not access to the patient, encounter, or form type. Authenticated core users can supply arbitrary formId, formDir, and encounterId values to sign and lock any patient's clinical form, creating unauthorized approval records and blocking normal editing.
