NVD Description

Note: Versions mentioned in the description apply only to the upstream tensorflow-cpu-jupyter package and not the tensorflow-cpu-jupyter package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

The nbconvert tool, jupyter nbconvert, converts Jupyter notebooks to various other formats via Jinja templates. In versions 6.5 through 7.17.0, when HTMLExporter.embed_images=True, nbconvert's markdown renderer allows arbitrary file read via path traversal in image references. A malicious notebook can exfiltrate sensitive files from the conversion host by embedding them as base64 data URIs in the output HTML. nbconvert 7.17.1 contains a fix. As a workaround, do not enable HTMLExporter.embed_images; it is not enabled by default.
