Company Profile
Markdown is a lightweight markup language created by John Gruber in 2004, designed for easy-to-read and easy-to-write plain text formatting that can be converted to HTML. Its primary product is the Markdown language specification and a reference implementation in Perl, which has become a de facto standard for documentation, readme files, and content creation across the software industry. While the project itself has minimal direct cybersecurity exposure, its widespread adoption means vulnerabilities in Markdown parsers and implementations can have broad security implications.
