CVE-2026-13147Public exploitNetwork attack vector

Unauthenticated server requests via unchecked URL

Published Jul 20, 2026 · Updated Jul 20, 2026

Server-side request forgery in Kirki before 6.0.12 allows remote attackers to make arbitrary HTTP requests through kirki_get_apis. The AJAX handler accepts an elementUrl from a guest nonce-bearing request and passes it to wp_remote_get without SSRF-safe URL validation. The unauthenticated path reaches loopback, private, link-local, and public hosts; arbitrary responses remain blind unless they contain Kirki-block JSON.
