Technical details

The /callback/order/unpaid endpoint lacks authentication checks, allowing any unauthenticated user to submit an orderSn parameter and trigger order cancellation. Order serial numbers are predictable, derived from epoch seconds and a sequential counter, enabling attackers to enumerate and cancel arbitrary unpaid orders. Successful exploitation restores product stock, enabling inventory manipulation and business disruption.
