What is CVE-2026-12073?

The ProfileGrid - User Profiles, Groups and Communities plugin for WordPress contains a vulnerability that allows unauthenticated attackers to exploit a lack of user login validation during registration. This oversight enables attackers to manipulate error messages and hijack the email account linked to the user ID=1 (typically the administrator). By doing so, they can reset the administrator's password and gain unauthorized access to the admin account, potentially compromising the entire website.
