CVE-2022-46161Public exploitNetwork attack vector

Remote code execution via dev-playground eval

Published Dec 6, 2022 · Updated Apr 22, 2025

Code injection in pdfmake 0.2.5 and earlier allows remote attackers to execute arbitrary code through the dev-playground /pdf endpoint. The endpoint passes req.body.content directly to eval() without sanitization or sandboxing, so supplied JavaScript runs in the Node.js server process. Exposure requires a source checkout with the developer playground running; published npm builds omit that component, and the maintainer disputes package applicability.
