funnelformsInteractive Contact Form and Multi Step Form Builder with Drag & Drop Editor – Funnelforms Free

Description#

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_copy_posts function. This makes it possible for unauthenticated attackers to create copies of arbitrary posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE-2023-5990 appears to be a duplicate of this issue.
