Summary

APTRS (Automated Penetration Testing Reporting System) is a Python and Django-based automated reporting tool designed for penetration testers and security organizations. Prior to version 2.0.1, the edit_user endpoint (POST /api/auth/edituser/<pk>) allows Any user who can reach that endpoint and submit crafted permission to escalate their own account (or any other account) to superuser by including "is_superuser": true in the request body. The root cause is that CustomUserSerializer explicitly includes is_superuser in its fields list but omits it from read_only_fields, making it a writable field. The edit_user view performs no additional validation to prevent non-superusers from modifying this field. Once is_superuser is set to true, gaining unrestricted access to all application functionality without requiring re-authentication. This issue has been patched in version 2.0.1.
