ProfileGrid – User Profiles, Groups and Communities <= 5.8.9 - Authenticated (Subscriber+) Authorization Bypass to Privilege Escalation

The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 5.8.9. This is due to a lack of validation on user-supplied data in the 'pm_upload_image' AJAX action. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update their user capabilities to Administrator.
