A privilege escalation issue exists due to a missing authorization check in the `CustomersController` REST controller located in `includes/REST/CustomersController.php`. The plugin re-registers WooCommerce customer CRUD routes under the `/dokan/v1/customers/` namespace and replaces the standard `manage woocommerce` capability check with a check that only verifies the role of the requesting user without validating the target user. Consequently, authenticated users with Vendor or Seller roles can read, modify, or delete any WordPress user, including administrators, by sending `GET`, `PUT`, or `DELETE` requests to the `/wp-json/dokan/v1/customers/{id}` endpoint. Specifically, modifying the `password` parameter of an administrator account can lead to a full site takeover.
