Prior to version 8.0.0.1, a stored cross-site scripting vulnerability in the prescription CSS/HTML multi-print feature allows a patient portal user to execute arbitrary JavaScript in a clinician\u0027s browser session. Patient demographic fields (name, address) are rendered without output encoding in multiprintcss_header(), and portal patients can write attacker-controlled HTML directly into patient_data by calling the PUT api/patient/:num endpoint, which bypasses the intended audit review workflow. Because the XSS fires in the clinician\u0027s authenticated session on the main OpenEMR interface, the attacker can access CSRF tokens, session data, and perform actions as the clinician \u2014 crossing the patient-to-clinician trust boundary.
