What is CVE-2023-5411?

The Funnelforms Free plugin for WordPress features a vulnerability that allows authenticated users, specifically those with subscriber-level and higher permissions, to alter post values. This issue stems from a missing capability check in the fnsf_af2_save_post function for versions up to and including 3.4, ultimately enabling unauthorized data modifications. While the changes that can be made are restricted due to fixed values during the wp_update_post function, the absence of proper checks poses a significant risk to data integrity.

Affected Version(s)

Interactive Contact Form and Multi Step Form Builder with Drag & Drop Editor – Funnelforms Free * <= 3.4
