If user-supplied Markdown is fed to md-to-pdf and the front-matter contains malicious JS, the converter process will execute that code. PoC Running the PoC on Windows launches the calculator application, demonstrating arbitrary code execution. Impact - Remote code execution in the process that performs Markdown-PDF conversion. - If the converter is run in a web app or cloud service, an attacker uploading malicious Markdown can execute arbitrary commands on the
