Vulnerability Description
The WP AutoBuzz plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.1. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update 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. This vulnerability bypasses WordPress's DISALLOW_UNFILTERED_HTML protection because the unsanitized value is written directly via update_option at the plugin level, entirely outside of WordPress post content handling.
