CVE-2025-53000
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. This issue has been patched in version 7.17.0.
