Unauthenticated user deletion via unchecked POST request
Published Mar 8, 2026 · Updated Mar 8, 2026
Improper authorization in SourceCodester Client Database Management System 1.0 allows remote attackers to delete arbitrary user accounts. The superadmin_user_delete.php endpoint accepts a POST user_id value and performs the deletion without checking session state or user role. No authenticated session or user interaction is required, and deletion can deny legitimate users access to the service.
