woocommerce_rest_private_query_vars хук-фильтр . WC 1.0

Filter the allowed 'private' query vars for authorized users.

If the user has the edit_posts capability, we also allow use of private query parameters, which are only undesirable on the frontend, but are safe for use in query strings.

To disable anyway, use add_filter('woocommerce_rest_private_query_vars','__return_empty_array');
