"CVE-2022-21697"
],
"details": "### Impact\n\n**What kind of vulnerability is it?** Server-Side Request Forgery ( SSRF )\n\n**Who is impacted?** Any user deploying Jupyter Server or Notebook with jupyter-proxy-server extension enabled. \n\nA 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.\n\n\n### Patches\n\n_Has the problem been patched? What versions should users upgrade to?_\n\nUpgrade to 3.2.1, or apply the patch https://github.com/jupyterhub/jupyter-server-proxy/compare/v3.2.0...v3.2.1.patch\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open a topic [on our forum](https://discourse.jupyter.org)\n* Email the Jupyter security team at [[email protected] ](mailto:[email protected] )\n",
