What is CVE-2026-2488?
CVE-2026-2488 is a medium-severity missing authorization vulnerability in metagauss ProfileGrid – User Profiles, Groups and Communities, published on 7 Mar 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to unauthorized message deletion due to a missing capability check on the pg_delete_msg() function in all versions up to, and including, 5.9.8.1. This is due to the function not verifying that the requesting user has permission to delete the targeted message. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary messages belonging to any user by sending a direct request with a valid message ID (mid parameter).
