Japanized for WooCommerce <= 2.7.17 - Missing Authorization to Unauthenticated Order Status Modification

The Japanized for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `order` REST API endpoint in all versions up to, and including, 2.7.17. This makes it possible for unauthenticated attackers to mark any WooCommerce order as processed/completed.
