CVE-2026-74020Network attack vector

Post disclosure via public AJAX query

Published Aug 20, 2026 · Updated Aug 20, 2026

Broken access control in the AJAX load-more handler in Anders Norén Koji 2.2.1 and earlier allows remote attackers to read post data via crafted AJAX queries. The public wp_ajax_nopriv_koji_ajax_load_more endpoint passes $_POST['json_data'] directly into WP_Query and renders matching previews without a capability check, nonce check, or allowlist on query arguments. Reachability is unauthenticated over /wp-admin/admin-ajax.php; published records indicate confidentiality impact only, and no public evidence reviewed here shows data modification or code execution.
