Table of Contents Plus <= 2302 - Cross-Site Request Forgery

The Table of Contents Plus plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2302. This is due to incorrect nonce validation on the save_admin_options() function. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
