AI-suggested
Until a fix is available, restricting access to the checkDelivery endpoint or implementing authentication controls is recommended.
Description
mall4j through 4.0 contains a missing authentication vulnerability in the DeliveryController checkDelivery endpoint that allows unauthenticated attackers to read shipment tracking information by supplying an order number parameter. Attackers can access carrier names, waybill numbers, and complete logistics trails for any order without authentication or ownership verification.
