SCA: security update for jupyterhub (GHSA-3vff-hjqv-m7h8)

medium Tenable Self-Hosted Container Security Plugin ID 440931

Description

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

- JupyterHub is software that allows one to create a multi-user server for Jupyter notebooks. Prior to
version 5.4.4, an open redirect vulnerability in JupyterHub allows attackers to construct links which,
when clicked, take users to the JupyterHub login page, after which they are sent to an arbitrary attacker-
controlled site outside JupyterHub instead of a JupyterHub page, bypassing JupyterHub's check to prevent
this. This issue has been patched in version 5.4.4. (CVE-2026-33709)

Solution

Update the jupyterhub library and its related packages to version 5.4.4 or later.
