What is CVE-2026-84225?

The Kirki plugin for WordPress prior to version 6.3.0 lacks proper validation of user permissions when modifying comments on the page builder. This oversight allows users with only content-level access to alter comments made by others, even on pages that they do not have access to view. As a result, there is a risk of unauthorized modifications to critical feedback or dialogues, potentially leading to misinformation or compromised content integrity.

Affected Version(s)

Kirki 6.0.0 < 6.3.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
