PYSEC-2020-234

Vulnerability from pysec - Published: 2020-11-24 21:15 - Updated: 2021-08-27 03:22

Details

Jupyter Server before version 1.0.6 has an Open redirect vulnerability. A maliciously crafted link to a jupyter server could redirect the browser to a different website. All jupyter servers are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may appear safe, but ultimately redirect to a spoofed server on the public internet.

GHSA-GRFJ-WJV9-4F9V

Vulnerability from github – Published: 2020-11-24 21:20 – Updated: 2024-09-23 19:28

Summary

Open redirect in Jupyter Server

Details

Impact

What kind of vulnerability is it? Who is impacted?

Open redirect vulnerability - a maliciously crafted link to a jupyter server could redirect the browser to a different website.

All jupyter servers are technically affected, however, these maliciously crafted links can only be reasonably made for known jupyter server hosts. A link to your jupyter server may appear safe, but ultimately redirect to a spoofed server on the public internet.

This originated in jupyter/notebook: https://github.com/jupyter/notebook/security/advisories/GHSA-c7vm-f5p4-8fqh

Patches

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

jupyter_server 1.0.6
