{"id":"CVE-2026-33911","state":"PUBLISHED","title":"OpenEMR vulnerable to reflected XSS in graphs.php via title parameter","description":"OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0.3, the POST parameter `title` is reflected back in a JSON response built with `json_encode()`. Because the response is served with a `text/html` Content-Type, the browser interprets injected HTML/script tags rather than treating the output as JSON. An authenticated attacker can craft a request that executes arbitrary JavaScript in a victim's session.
