This vulnerability permits unauthenticated attackers to access sensitive information. Such breaches pose a significant threat to server security, especially for system administrators and hosting providers.

Understanding the Vulnerability

Versions of the NEX-Forms plugin, up to and including 9.2.2, fail to verify user authorization adequately.
