Vulnerability Overview

The FuseWP plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.24.2. This is due to missing nonce verification on the toggle_sync_status() function. This makes it possible for unauthenticated attackers to toggle the status of sync rules (enable/disable) via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
