ProfileGrid – User Profiles, Memberships, Groups and Communities <= 5.0.3 - Missing Authorization to Information Exposure

The ProfileGrid – User Profiles, Memberships, Groups and Communities plugin for WordPress is vulnerable to authorization bypass due to a missing capability check when accessing messages in versions up to, and including, 5.0.3. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to obtain access to arbitrary messages with read and edit capabilities.
