What is CVE-2026-12723?

The Kirki WordPress plugin prior to version 6.0.12 contains a significant vulnerability in that it fails to implement necessary authorization checks on one of its REST routes. This oversight permits unauthenticated users to not only overwrite existing comments but also to create comments that are approved through misleading identities. As a result, this vulnerability circumvents standard comment moderation protocols, posing a risk to content integrity and user trust.

Affected Version(s)

Kirki 0 < 6.0.12

Exploit Proof of Concept (PoC)
