Description · from the CVE record

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.
