Vulnerability Overview

The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.

Technical Analysis

REMEDIATION: Update to version 260215, or a newer patched version --- IDENTIFIER: CWE-269 (Improper Privilege Management) The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
