CVE-2026-8761

Descripción

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.
