The FastPicker, an order picker and order management system (oms) for WooCommerce on steroids plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.2. This is due to missing or incorrect nonce validation on the settingsPage function. This makes it possible for unauthenticated attackers to modify the plugin's settings, including toggling the webhook integration and changing the FastPicker and KDZ API URLs via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
