CVE-2026-14693Public exploitNetwork attack vector

Cross-account order cancellation via missing ownership check

Published Jul 5, 2026 · Updated Jul 5, 2026

Improper authorization in SourceCodester Multi-Vendor Online Groceries Management System 1.0 allows remote authenticated users to cancel any order. The cancel_order function in classes/Master.php uses a client-supplied id as the only selector in an order_list UPDATE and never checks the order's client_id against the authenticated session. Any registered client can therefore cancel another client's order; public self-registration supplies the low-privilege account needed to reach the endpoint.
