## Overview

PublicCMS through V6.202608.a contains an insecure direct object reference vulnerability in the TradeAddressController tradeAddress/save handler that allows authenticated members to modify other members' shipping addresses. Attackers can submit another member's sequential numeric address id to overwrite its addressee, telephone and address fields, since ownership by the session user and site is never verified.
