# waynboot-mall: unauthenticated callback cancels members' unpaid orders

The waynboot-mall shop application exposes an order callback endpoint, /callback/order/unpaid, that does not check authentication. An attacker can cancel any member's pending order and change product stock levels by guessing predictable order numbers.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
