SCA: security update for jupyterlab (GHSA-pppj-hq3g-57pj)

high Tenable Self-Hosted Container Security Plugin ID 445129

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 3.3.0 until 4.5.10 and 4.6.2, JupyterLab allows notebook settings to be shared
 and applied through an overrides.json file using the Import button in the Settings Editor. In
 packages/notebook-extension/schema/tracker.json and packages/notebook-extension/src/index.ts, the
 sideBySideLeftMarginOverride and sideBySideRightMarginOverride settings are not properly validated before
 being inserted into style content, allowing a crafted settings file to contain instructions that execute
 as code instead of only changing display preferences. A user can import the malicious file, or an attacker
 with access to a shared settings location can plant an overrides.json that is applied automatically. The
 embedded code runs with the affected user's access and can read or modify notebooks and files and run code
 through the notebook server, including on a connected kernel. This issue is fixed in versions 4.5.10 and
 4.6.2. (CVE-2026-73417)

Solution

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