What is CVE-2026-12687?

The ProfileGrid WordPress plugin prior to version 5.9.9.8 contains a security flaw that allows anonymous users to bypass registration restrictions. As a result, these users can register into privileged groups without authentication, potentially being assigned roles with elevated permissions, including that of an Administrator. This loophole poses a significant risk, enabling unauthorized access to sensitive areas of the website and compromising site integrity.

Affected Version(s)

ProfileGrid 0 < 5.9.9.8
