Mitigating Controls (NIST 800-53 r5) AI
Directly enforces access control policies on the /admin/core/import_users.php endpoint to block unauthenticated file uploads for bulk user import.
Ensures the Bulk Import function is restricted to only authorized privileged roles, eliminating the CWE-266 incorrect privilege assignment that allows anonymous access.
Requires successful identification and authentication of organizational users before any access to the import functionality is granted, closing the unauthenticated remote attack path.
