nbconvert has an uncontrolled search path that leads to unauthorized code execution on Windows
On Windows, 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.
