How to Fix CVE-2024-22421

To remediate this vulnerability, upgrade all affected Jupyterlab dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

jupyterlab fixed: 4.0.11 
pip install jupyterlab>=4.0.11
jupyterlab fixed: 3.6.7 
pip install jupyterlab>=3.6.7
notebook fixed: 7.0.7 
pip install notebook>=7.0.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show jupyterlab

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-22421, inspect your installed packages using pip:

pip show jupyterlab

Analyze the terminal output to locate any version of Jupyterlab in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.11), your application is affected.

Note: The pip show jupyterlab command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Jupyterlab, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Users of JupyterLab who click on a malicious link may get their `Authorization` and `XSRFToken` tokens exposed to a third party when running an older `jupyter-server` version. ### Patches JupyterLab 4.1.0b2, 4.0.11, and 3.6.7 were patched. ### Workarounds No workaround has been identified, however users should ensure to upgrade `jupyter-server` to version 2.7.2 or newer which includes a redirect vulnerability fix. ### References Vulnerability reported by user @davwwwx via the [bug bounty program](https://app.intigriti.com/programs/jupyter/jupyter/detail) [sponsored by the European Commission](https://commission.europa.eu/news/european-commissions-open-source-programme-office-starts-bug-bounties-2022-01-19_en) and hosted on the [Intigriti platform](https://www.intigriti.com/).
