A stored cross-site scripting (XSS) vulnerability exists in Phpgurukul Cyber Cafe Management System v1.0 within the user management module. The application does not properly sanitize or encode user-supplied input submitted via the uadd parameter in the add-users.php endpoint. An authenticated attacker can inject arbitrary JavaScript code that is persistently stored in the database. The malicious payload is triggered when a privileged user clicks the View button on the view-allusers.php page.
