OpenEMR before 8.5.0 contains a stored cross-site scripting vulnerability that allows users with admin/superbill write permission to inject HTML into SNOMED code descriptions via superbill custom full.php. When a clinician selects the malicious code, the Functional and Cognitive Status form or fee-sheet forms assign it to innerHTML, executing JavaScript in the clinician's session to read patient data and perform actions.
