Quick fix

PYSEC-2020-234 — jupyter-server: upgrade to the fixed version with the command below.

pip install --upgrade 'jupyter-server>=3d83e49090289c431da253e2bdb8dc479cbcb157'

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.
