Advisory
Source description from Wordfence Intelligence, credited to Ryoma Nishioka.
The Meta Data Filter & Taxonomies Filter plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions versions prior to v.2.2.8. This is due to missing or incorrect nonce validation on the draw_settings_page() function. This makes it possible for unauthenticated attackers to inject malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
