Description: waynboot-mall through 2.0.0 contains a missing authentication vulnerability that allows unauthenticated attackers to cancel any member's pending order via the /callback/order/unpaid endpoint. Attackers can submit predictable orderSn values, built from epoch seconds and a sequential counter, to auto-cancel unpaid orders and manipulate product stock levels.
