Description: Yshopmall through 2.0.0 contains an insecure direct object reference vulnerability in the after-sales API that allows authenticated members to access other members' data by supplying their after-sales id and orderCode. Attackers can call deleteAfterSalesOrder, addLogisticsInformation, or GET /applyForAfterSales/{key} to view other members' order items and tamper with or delete their after-sales records.
