 "title": "WCFM Marketplace <= 3.8.3 - Authenticated (Store Vendor+) Missing Authorization to Refund Request Approval and Rejection",
 "description": "The WCFM Marketplace plugin for WordPress is vulnerable to unauthorized modification of data in all versions up to, and including, 3.8.3 due to an insufficient capability check on the 'wcfm-refund-requests-approve' and 'wcfm-refund-requests-cancel' AJAX actions, which allowed any vendor or vendor staff member, and did not prevent already completed requests from being approved again. This makes it possible for authenticated attackers with vendor-level access to approve or reject other vendors' refund requests, creating real refunds on other stores' orders, altering their commissions, and repeatedly refunding the same order.",
