CVE-2026-14488Network attack vector

Unauthenticated post deletion via unchecked dispatcher

Published Jul 29, 2026 · Updated Jul 29, 2026

Missing authorization in Meta Box AIO 3.8.0 and earlier allows remote attackers to delete arbitrary WordPress posts and pages. The MB Frontend Submission handle_request() dispatcher routes mbfs_delete with an attacker-controlled rwmb_frontend_field_object_id but performs no capability or ownership check, while check_ajax() skips nonce verification for template_redirect requests. No authentication is required; any page hosting a frontend submission form exposes deletion even when allow_delete is disabled.
