Advisory

Source description from Wordfence Intelligence, credited to Noah Stead (TurtleBurg).

The WordPress Header Builder Plugin – Pearl plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.3.8. This is due to missing or incorrect nonce validation on the stm_header_builder page. This makes it possible for unauthenticated attackers to delete arbitrary headers via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
