ProfileGrid – User Profiles, Groups and Communities <= 5.9.9.6 - Unauthenticated Privilege Escalation via Password Reset

The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 5.9.9.6. This is due to the plugin not properly validating a user's identity prior to updating their details like 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.
