What is CVE-2026-16290?

The ProfileGrid WordPress plugin versions prior to 6.0.0.0 suffer from a serious vulnerability that allows any unauthenticated visitor to access the member lists of various groups without proper authorization checks. This flaw exposes sensitive information, including member identifiers from private or closed groups, directly contravening the intended member-visibility settings established by the plugin. This creates significant privacy risks and necessitates immediate attention from users to ensure adequate protection.

Affected Version(s)

ProfileGrid 0 < 6.0.0.0

Exploit Proof of Concept (PoC)
