Technical details
The vulnerability is an authorization bypass in the reverse-withdrawal payment processing logic (CWE-863). When a vendor submits a payment amount via the REST API endpoint `/wp-json/dokan/v1/reverse-withdrawal/add-to-cart`, the plugin does not validate that the supplied amount matches the vendor's actual outstanding balance. The attacker must be an authenticated, approved vendor with a real due commission balance. An attacker can craft a reverse-withdrawal cart item with an inflated amount, complete checkout using Cash on Delivery (which requires no actual payment), and after the marketplace admin marks the order completed, the plugin credits the full arbitrary amount to the vendor's ledger. The plugin was patched in version 5.0.14.
