Detailed vulnerability description
The vulnerability allows a remote user to modify the category of any user.
The vulnerability exists due to missing authorization in the category update functionality when handling requests with a modified "category_id" parameter. A remote user can send a crafted request with a replaced "category_id" parameter to modify the category of any user.
The "category_id" parameter is numeric and incremental, which may facilitate brute-force attempts against the endpoint.
