Description¶
The Dokan plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 5.0.1. This is due to a missing authorization check in the CustomersController REST controller (includes/REST/CustomersController.php), which re-registers WooCommerce's customer CRUD routes under the /dokan/v1/customers/ namespace and replaces WooCommerce's native manage_woocommerce capability check with a vendor-only check that inspects the requesting user's role and never validates the target user. This makes it possible for authenticated attackers with Vendor/Seller-level access and above to read, modify, or delete any WordPress user — including administrators — via GET/PUT/DELETE requests against /wp-json/dokan/v1/customers/{id}. Setting the password parameter on an administrator's record yields a full site takeover.
