SCA: security update for jupyterhub (GHSA-cw7p-q79f-m2v7)

medium Tenable Self-Hosted Container Security Plugin ID 414131

Description

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

 - JupyterHub is an open source multi-user server for Jupyter notebooks. In affected versions users who have
 multiple JupyterLab tabs open in the same browser session, may see incomplete logout from the single-user
 server, as fresh credentials (for the single-user server only, not the Hub) reinstated after logout, if
 another active JupyterLab session is open while the logout takes place. Upgrade to JupyterHub 1.5. For
 distributed deployments, it is jupyterhub in the _user_ environment that needs patching. There are no
 patches necessary in the Hub environment. The only workaround is to make sure that only one JupyterLab tab
 is open when you log out. (CVE-2021-41247)
