Staff-session script execution via unsanitized signer name
Published Mar 11, 2026 · Updated Mar 11, 2026
Stored DOM XSS in OpenEMR before 8.0.0.1 allows remote authenticated users to execute JavaScript in a staff browser via a malicious patient name. The callModal function passes a patient name from patient_data through JSON parsing to jQuery .html() without HTML encoding in portal/sign/assets/signer_api.js. Exploitation requires patient self-registration and a staff member opening the attacker's signature modal, where script runs with the staff session's access.
