SCA: security update for jupyterlab (GHSA-89vp-jrxv-24w8)

medium Tenable Self-Hosted Container Security Plugin ID 445177

Description

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

 - jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter
 Notebook Architecture. From 4.5.0 until 4.5.10 and 4.6.2, in jupyterlab/extensions/manager.py and
 jupyterlab/extensions/pypi.py, JupyterLab's PyPI extension manager enforces blocked_extensions_uris by
 comparing requested install names to blocklist entries with custom normalization that is weaker than PyPI
 package-name canonicalization. An authenticated user can request a PyPI-equivalent spelling such as
 JupyterLab.Git for a blocklisted package such as jupyterlab-git, and JupyterLab accepts the install
 request even though pip resolves the variant to the same package. Security impact requires an allowlist or
 blocklist intended to restrict package installation, the PyPI Extension Manager, and kernels and terminals
 that are disabled or delegated to remote hosts. The bypass lets an authenticated user install a prohibited
 extension, defeat integrity restrictions, and affect availability without gaining new read access. This
 issue is fixed in versions 4.5.10 and 4.6.2. (CVE-2026-73416)

Solution

Update the jupyterlab library and its related packages to version 4.5.10 or later.
