CVE-2022-21697: SSRF vulnerability in jupyter-server-proxy
(updated )
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.
