Vulnerability Overview

The Smart Forms plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the smart_forms_save_settings() function hooked via AJAX in versions up to, and including, 2.6.84. This makes it possible for authenticated attackers, with subscriber-level access and above, to update arbitrary options which can be used for remote code execution.

Technical Analysis

REMEDIATION: Update to version 2.6.85, 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.
