CVE-2022-41710: Markdownify has Files or Directories Accessible to External Parties

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.

Root Cause Analysis

The vulnerability stems from two key issues: 1) Lack of input sanitization in markdown-to-HTML conversion allows arbitrary script execution (CWE-552 vector), and 2) Missing Electron security hardening measures (CSP + nodeIntegration settings) enables cross-platform filesystem access. While exact function names aren't visible in provided resources, Electron architecture patterns and the exploit's requirements make these components clearly vulnerable. The <img> onerror payload demonstration confirms renderer.process script execution capability, which would require both the markdown parser to allow unsafe HTML and the Electron context to permit Node.js filesystem access.
