Vulnerability Overview

The Funnelforms Free plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the fnsf_af2_save_post function in versions up to, and including, 3.4. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to modify certain post values. Note that the extent of modification is limited due to fixed values passed to the wp_update_post function.

Technical Analysis

REMEDIATION: Update to version 3.4.2, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
