Vulnerability Overview

The Comments – wpDiscuz plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 7.6.39. This is due to the plugin not properly validating a user's identity through the disqus.com provider. This makes it possible for unauthenticated attackers to authenticate as other users if they have not set up disqus.

Technical Analysis

REMEDIATION: Update to version 7.6.40, or a newer patched version --- IDENTIFIER: CWE-639 (Authorization Bypass Through User-Controlled Key) The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
