Hi,
The following vulnerability was published for nbconvert.
CVE-2026-39378[0]:
| 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.
