What is CVE-2025-13842?
CVE-2025-13842 is a medium-severity missing authorization vulnerability in mtekk Breadcrumb NavXT, published on 19 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
