The Funnelforms Free plugin for WordPress is vulnerable to a type of attack called Cross-Site Request Forgery. This vulnerability affects versions up to and including 3.4. It is caused by incorrect or missing security measures called nonce validation on the fnsf_delete_posts function. If an unauthenticated attacker can trick a site administrator into clicking on a link, they can use a forged request to delete arbitrary posts.
