CVE-2026-110113 · Severity: medium · CVSS 4.3 · Published 2026-10-13

PublicCMS is a Java-based content management system with an e-commerce trade module that stores customer shipping addresses. An authenticated attacker can modify other users' shipping addresses by directly referencing their numeric address IDs, overwriting the recipient name, phone number, and address without permission. This could enable account takeover through address manipulation during checkout or fraud against other site members.

## Technical details

The TradeAddressController.save endpoint accepts a user-supplied address ID and passes it directly to a generic update method without verifying ownership. The vulnerable code path loads the target row by primary key alone and overwrites fields (addressee, telephone, address) without checking that the address belongs to the authenticated user or site. Authentication (login) and CSRF tokens are enforced but do not provide object-level authorization; the delete handler in the same controller correctly implements ownership checks, showing the gap was unintended.
