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.
