## Technical details

Stored cross-site scripting (XSS) exists in feedback.php where user-supplied input from the msg parameter is directly inserted into a database without sanitization, and later rendered without HTML encoding in adminfeedbackview.php. The vulnerability requires no authentication to submit feedback but affects authenticated administrators who view the feedback list, allowing arbitrary JavaScript execution in their browser context.
