Description
OpenEMR before 8.5.0 contains a stored cross-site scripting vulnerability in printed_fee_sheet.php that allows authenticated portal patients to inject script by setting unescaped appointment comments (pc_hometext). Attackers can submit HTML payloads via the form_comments field in add_edit_event_user.php that execute when staff open the patient's fee sheet, acting within the staff session.
