How to fix?

Upgrade Chainguard tensorflow-gpu-jupyter to version 2.21.0-r6 or higher.

NVD Description

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

Jupyter Server is the backend for Jupyter web applications. Prior to 2.20, the nbconvert HTTP handlers in jupyter_server render user-authored notebook HTML under the Jupyter origin without a sandbox directive in their Content-Security-Policy. Combined with nbconvert.HTMLExporter's default non-sanitizing behavior, a notebook carrying an HTML payload in a display_data output triggers stored XSS with cookie access, full /api/* authority, and kernel RCE. This vulnerability is fixed in 2.20.
