Description
md-to-pdf is a CLI tool for converting Markdown files to PDF using Node.js and headless Chrome. Prior to version 5.2.5, a Markdown front-matter block that contains JavaScript delimiter causes the JS engine in gray-matter library to execute arbitrary code in the Markdown to PDF converter process of md-to-pdf library, resulting in remote code execution. This issue has been patched in version 5.2.5.

Executive Summary

This vulnerability exists in the md-to-pdf tool prior to version 5.2.5, where a Markdown front-matter block containing a JavaScript delimiter causes the gray-matter library's JavaScript engine to execute arbitrary code during the Markdown to PDF conversion process. This leads to remote code execution on the system running the converter.

Impact Analysis

The vulnerability can allow an attacker to execute arbitrary code remotely on the system running the md-to-pdf tool, potentially leading to full system compromise, data loss, or unauthorized control over the affected environment.

Mitigation Strategies

Upgrade the md-to-pdf tool to version 5.2.5 or later, as this version contains the patch that fixes the remote code execution vulnerability caused by the JavaScript delimiter in Markdown front-matter blocks.
