## Description

The PNG to JPG plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 4.5 due to missing nonce validation on the 'yoast_reindex_everything' action of the plugin's settings page. This makes it possible for unauthenticated attackers to delete the contents of the Yoast SEO indexable tables via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
