CVE-2026-111660
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.
Does this matter?
Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.
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.
