AI Analysis
Technical Summary
The MultiVendorX WordPress plugin before version 5.0.16 fails to verify that a user owns the store they are modifying in one of its REST API endpoints. This missing authorization (CWE-862) enables any authenticated user to overwrite details and payout settings of any store, including replacing the ownership record. The vulnerability affects versions from 5.0.0 up to but excluding 5.0.16.
