Vulnerability Overview

The NextScripts: Social Networks Auto-Poster plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on multiple user privilege/security functions provided in versions up to, and including 4.3.17. This makes it possible for low-privileged attackers, like subscribers, to perform restricted actions that would be otherwise locked to a administrative-level user.

Technical Analysis

REMEDIATION: Update to version 4.3.18, or a newer patched version --- IDENTIFIER: CWE-284 (Improper Access Control) The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
