Date: December 17, 2025

The nbconvert tool, jupyter nbconvert, converts Jupyter notebooks to various other formats via Jinja templates. Versions of nbconvert up to and including 7.16.6 on Windows have a vulnerability in which converting a notebook containing SVG output to a PDF results in unauthorized code execution. Specifically, a third party can create a "inkscape.bat" file that defines a Windows batch script, capable of arbitrary code execution. When a user runs "jupyter nbconvert --to pdf" on a notebook containing SVG output to a PDF on a Windows platform from this directory, the "inkscape.bat" file is run unexpectedly. As of time of publication, no known patches exist.
