An issue was discovered in Munkireport before 5.3.0.3923. An unauthenticated actor can send a custom XSS payload through the /report/broken_client endpoint. The payload will be executed by any authenticated users browsing the application. This concerns app/views/listings/default.php.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
