CVE-2025-13842Network attack vector

Unauthenticated draft metadata disclosure via trusted post_id

Published Feb 19, 2026 · Updated Feb 19, 2026

Authorization bypass in mtekk Breadcrumb NavXT 7.5.0 and earlier allows remote attackers to view breadcrumb trails for unpublished posts. The Gutenberg block renderer in includes/blocks/build/breadcrumb-trail/render.php accepts the request post_id value as the current post without checking its publication status or access authorization. No authentication is required, and crafted post_id values disclose draft or private post titles and hierarchy without exposing post bodies or permitting changes.
