Arbitrary command execution via shell-enabled PDF import
Published Dec 7, 2022 · Updated Apr 23, 2025
OS command injection in Markdown Preview Enhanced 0.6.5 and 0.19.6 allows attackers to execute commands through a crafted PDF import. In pdf.ts, the PDF conversion path inserts the import's pdfFilePath into pdf2svg arguments and calls child_process.spawn with shell execution enabled. Exploitation requires a user to open the preview of a malicious Markdown document, after which the injected command runs with the editor user's privileges.
