Advisory

Source description from Wordfence Intelligence, credited to Duc Manh.

The Funnelforms Free plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.4. This is due to missing or incorrect nonce validation on the fnsf_delete_posts function. This makes it possible for unauthenticated attackers to delete arbitrary posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
