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.
