npm install electron-markdownify@Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls electron-markdownify

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2022-41710, inspect your project dependencies using npm:

npm ls electron-markdownify

Analyze the terminal output to locate any version of Electron markdownify in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls electron-markdownify command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-552: Files or Directories Accessible to External Parties, where the product makes files or directories accessible to unauthorized actors, even though they should not be. In Electron markdownify, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Markdownify version 1.4.1 allows an external attacker to remotely obtain arbitrary local files on any client that attempts to view a malicious markdown file through Markdownify. This is possible because the application does not have a CSP policy (or at least not strict enough) and/or does not properly validate the contents of markdown files before rendering them.
