CVE-2026-112294
MediumCVSS 4.3Summary
FlyCms through commit edfdf724 contains a missing authorization vulnerability in ActionService.counter() that allows authenticated users to modify other users' content rows because checkRowOwner never verifies ownership.

Risk Assessment
Any registered user can modify other users' data, including prices, stock, and points, potentially leading to financial fraud and data integrity violations.

Update FlyCms to a version containing the fix after commit edfdf724. Until patched, consider restricting access to the /ucenter/action endpoints.
