Yshopmall vulnerabilities

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.

Yshopmall through 2.0.0 contains an insecure direct object reference (IDOR) vulnerability in the member address API. Authenticated members can read, overwrite, and delete other members' shipping addresses by enumerating sequential address IDs via /address/detail/{id}, /address/del, and /address/edit.

In yshopmall version 3.3 and earlier, there is a Cross Site Scripting (XSS) vulnerability. The file upload endpoint /api/upload lacks file type validation. Attackers can upload files of any type, including HTML, JSP, and other executable files.
