What is CVE-2026-84222?

The Kirki WordPress plugin, prior to version 6.3.0, contains a vulnerability that allows unauthenticated users to access private content. This issue arises because the plugin fails to verify whether a requester is authorized to view certain pages, including those marked as private, draft, or trashed. This oversight can lead to unauthorized exposure of sensitive information and presents a significant risk to site owners who rely on the plugin for managing content visibility.

Affected Version(s)

Kirki 6.2.1 < 6.3.0

Exploit Proof of Concept (PoC)
