CVE-2026-1112Public exploitNetwork attack vector

Authenticated address deletion via missing ownership check

Published Jan 18, 2026 · Updated Jan 18, 2026

Improper authorization in PublicCMS 5.202506.a through 5.202506.d allows remote authenticated users to delete other users' trade addresses. TradeAddressController.delete passes attacker-selected address IDs to service.delete, whose database deletion filters by address ID without comparing the stored userId with the session user's ID. Any authenticated account with a valid CSRF token can remove saved shipping addresses it does not own, causing persistent loss of those address records.
