The MetaMagic SEO Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.6. This is due to missing or incorrect nonce validation on the metamagic update options function. This makes it possible for unauthenticated attackers to modify the plugin's SEO settings, including enabling or disabling the plugin and toggling description and keyword meta tag output via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
