Brands for WooCommerce <= 3.8.2.2 - Cross-Site Request Forgery

The Brands for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.8.2.2. This is due to missing nonce validation on the clear_cache_ajax, save_order, and save_all_orders functions hooked via AJAX actions. This makes it possible for unauthenticated attackers to modify orders and clear the plugin's cache via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
