Technical details

This is a reflected cross-site scripting (XSS) vulnerability in index.php where the msg query parameter is echoed directly into an HTML alert div without output encoding (htmlspecialchars/htmlentities). An unauthenticated attacker can craft a malicious URL containing JavaScript payload in the msg parameter, and when a user visits that URL, the script executes in the browser with the application's origin context. The vulnerable code prints $_GET["msg"] directly into the HTML without sanitization. User interaction (clicking the link) is required, but no authentication is needed. The attack impacts confidentiality and integrity by enabling credential theft, session hijacking, or UI forgery on the login page.
