ProfileGrid – User Profiles, Groups and Communities < 5.9.7.3 - Missing Authorization to Authenticated (Subscriber+) Arbitrary User Suspension

Description

The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to unauthorized user suspension due to a missing capability check on the pm_deactivate_user_from_group() function in all versions up to, and including, 5.9.7.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to suspend arbitrary users from groups, including administrators, via the pm_deactivate_user_from_group AJAX action.
