Breadcrumb NavXT, CVE-2025-13842

CVE, Research URL: CVE-2025-13842
Home page URL: Security reports for Breadcrumb NavXT
Application: Breadcrumb NavXT
Published on: Feb 19, 2026
Research Description: The Breadcrumb NavXT plugin for WordPress is vulnerable to authorization bypass through user-controlled key in versions up to and including 7.5.0. This is due to the Gutenberg block renderer trusting the $_REQUEST['post_id'] parameter without verification in the includes/blocks/build/breadcrumb-trail/render.php file. This makes it possible for unauthenticated attackers to enumerate and view breadcrumb trails for draft or private posts by manipulating the post_id parameter, revealing post titles and hierarchy that should remain hidden.
Affected versions: max 7.5.1.
Status: vulnerable
