What is CVE-2026-110113?

PublicCMS versions up to V6.202608.a are susceptible to an insecure direct object reference vulnerability in the TradeAddressController's tradeAddress/save handler. This issue permits authenticated users to manipulate other users' shipping addresses by submitting a sequential numeric address ID. Since the application does not verify the ownership of the request against the session user or site, attackers can overwrite critical user fields such as addressee, telephone, and address, posing a significant risk to user data privacy.
