Summary
PublicCMS through V6.202608.a contains an insecure direct object reference in the TradeAddressController tradeAddress/save handler (CWE-639). An authenticated member can submit another member's sequential numeric address id to overwrite that member's addressee, telephone and address fields, because ownership by the session user and site is never verified. CISA SSVC rates exploitation as PoC and technical impact as partial, and the CVSS 4.0 vector requires low privileges and no user interaction.
