ProfileGrid – User Profiles, Memberships, Groups and Communities < 5.8.0 - Insecure Direct Object Reference

Description The ProfileGrid – User Profiles, Memberships, Groups and Communities plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.7.9 due to missing validation on a user controlled key in the pg_show_msg_panel() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to view other’s messages.
