Description: Yshopmall through 2.0.0 contains an insecure direct object reference vulnerability in the member address API that allows authenticated members to read, overwrite and delete other members' shipping addresses. Attackers can enumerate sequential address ids via /address/detail/{id}, /address/del and /address/edit to expose recipient names, phone numbers and addresses, reassign them, or delete them.
