CVE-2022-41710Public exploit

Local file disclosure via rendered JavaScript

Published Nov 3, 2022 · Updated May 5, 2025

Local file disclosure in Markdownify 1.4.1 allows attackers to read arbitrary files by inducing a user to open malicious Markdown. Its live preview renders embedded JavaScript from the document without an effective Content Security Policy or adequate content validation, letting script fetch local file resources. Exploitation requires a user to open the crafted file, and the demonstrated consequence is disclosure of files readable by the application.
