## Technical details

The vulnerability is a reflected cross-site scripting (XSS) flaw in the GET Parameter Handler component, specifically in /includes/header_menu.php where the "Error" parameter is insufficiently sanitized. An unauthenticated attacker can craft a malicious URL containing JavaScript payload in the Error parameter and trick users into clicking the link, causing the payload to execute in the victim's browser within the application context. The attack requires user interaction (clicking a link) and is remotely exploitable. A public exploit is available, though no patch from the vendor has been provided.
