CVE-2022-4733Public exploitNetwork attack vector

Stored script execution via unsafe support links

Published Dec 24, 2022 · Updated Apr 10, 2025

Stored XSS in OpenEMR before 7.0.0.2 allows remote authenticated users to execute script through crafted About-page link settings. The About template places stored support-phone, online-support, and user-manual values into link targets without rejecting the javascript scheme. High-privilege configuration access is required to store the values, and another user must activate a rendered link to execute script in the OpenEMR origin.
