Vulnerability in Kirki – Freeform Page Builder, Website Builder & Customizer — CVE-2026-75891

What to do now

Update Kirki – Freeform Page Builder, Website Builder & Customizer to 6.3.0 or later.

Affected versions

• Everything up to and including 6.2.5

The Kirki plugin for WordPress is vulnerable to Privilege Escalation via PHP Object Injection in all versions up to, and including, 6.2.5 via deserialization of untrusted input through the 'get-single-symbol' branch of the kirki_post_apis() AJAX dispatcher due to a missing capability check. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to overwrite an administrator's password and gain administrative access.
