Description
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.
