How to Fix CVE-2019-9644

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

jupyter-notebook fixed: 5.7.6 
pip install jupyter-notebook>=5.7.6
notebook fixed: 5.7.6 
pip install notebook>=5.7.6
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 jupyter-notebook

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-9644, inspect your installed packages using pip:

pip show jupyter-notebook

Analyze the terminal output to locate any version of Jupyter notebook in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.7.6), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Jupyter notebook, 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

An XSSI (cross-site inclusion) vulnerability in Jupyter Notebook before 5.7.6 allows inclusion of resources on malicious pages when visited by users who are authenticated with a Jupyter server. Access to the content of resources has been demonstrated with Internet Explorer through capturing of error messages, though not reproduced with other browsers. This occurs because Internet Explorer's error messages can include the content of any invalid JavaScript that was encountered.
