Mautic Integration for WooCommerce < 1.0.3 - Cross-Site Request Forgery leading to Arbitrary Options Update

The Mautic Integration for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, but not including, 1.0.3. This is due to missing or incorrect nonce validation when updating plugin settings. Further, the options being updated are not checked properly to restrict them to the plugin's own settings. This makes it possible for unauthenticated attackers to change arbitrary WordPress options granted they can trick a site administrator into performing an action such as clicking on a link.
