Vulnerability Title
OpenEMR: Stored DOM XSS via `.html()` in Portal Signer Modal
Source: CVE Program / CVE List V5
Vulnerability Description
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.1, Stored XSS in prescription CSS/HTML print view via patient demographics. That finding involves server-side rendering of patient names via raw PHP echo. This finding involves client-side DOM-based rendering via jQuery .html() in a completely different component (portal/sign/assets/signer_api.js). The two share the same root cause (unsanitized patient names in patient_data), but they have different sinks, different affected components, different trigger actions, and require independent fixes. This vulnerability is fixed in 8.0.0.1.
