Description

The Custom Options Plus plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.8.1. This is due to missing nonce validation on the custom_options_plus_adm() 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.
