Description
The OPEN-BRAIN plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.5.0. This is due to missing nonce verification on the settings form in the func_page_main() function. This makes it possible for unauthenticated attackers to inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
