SCA: security update for jupyter-server (GHSA-9f66-54xg-pc2c)

medium Tenable Cloud Security Plugin ID 413236

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web
 applications like Jupyter notebook, JupyterLab, and Voila. In Jupyter Server before version 1.1.1, an open
 redirect vulnerability could cause the jupyter server to redirect the browser to a different malicious
 website. All jupyter servers running without a base_url prefix 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
 same vulnerability was patched in upstream notebook v5.7.8. This is fixed in jupyter_server 1.1.1. If
 upgrade is not available, a workaround can be to run your server on a url prefix: "jupyter server
 --ServerApp.base_url=/jupyter/". (CVE-2020-26275)
