Vulnerability Overview

The JSON API User plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 3.9.3. This is due to improper controls on custom user meta fields. This makes it possible for unauthenticated attackers to register as administrators on the site. The plugin requires the JSON API plugin to also be installed.

Technical Analysis

REMEDIATION: Update to version 3.9.4, 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.
