VLAI?
Summary
SSRF vulnerability in jupyter-server-proxy
Details

Impact

What kind of vulnerability is it? Server-Side Request Forgery ( SSRF )

Who is impacted? Any user deploying Jupyter Server or Notebook with jupyter-proxy-server extension enabled.

A lack of input validation allowed authenticated clients to proxy requests to other hosts, bypassing the allowed_hosts check. Because authentication is required, which already grants permissions to make the same requests via kernel or terminal execution, this is considered low to moderate severity.

Patches

Has the problem been patched? What versions should users upgrade to?

Upgrade to 3.2.1, or apply the patch https://github.com/jupyterhub/jupyter-server-proxy/compare/v3.2.0...v3.2.1.patch
