Cross-Site Request Forgery Vulnerability in Floating Social Buttons Plugin

Summary

The Floating Social Buttons plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5. This is due to missing or incorrect nonce validation on the floating_social_buttons_option() function. This makes it possible for unauthenticated attackers to update the plugins settings and 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.
