Vulnerability from github – Published: 2022-11-04 12:00 – Updated: 2022-11-04 20:49

Summary

Markdownify has Files or Directories Accessible to External Parties

Details

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.

Severity

5.5 (Medium)
