How to Fix CVE-2022-39286

To remediate this vulnerability, upgrade all affected Jupyter core 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-core fixed: 4.11.2 
pip install jupyter-core>=4.11.2
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-core

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-39286, inspect your installed packages using pip:

pip show jupyter-core

Analyze the terminal output to locate any version of Jupyter core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.11.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-269: Improper Privilege Management, where the product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. In Jupyter core, 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 _What kind of vulnerability is it? Who is impacted?_ We’d like to disclose an arbitrary code execution vulnerability in `jupyter_core` that stems from `jupyter_core` executing untrusted files in the current working directory. This vulnerability allows one user to run code as another. ### Patches _Has the problem been patched? What versions should users upgrade to?_ Users should upgrade to `jupyter_core>=4.11.2`. ### Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ No ### References _Are there any links users can visit to find out more?_ Similar advisory in [IPython](https://github.com/advisories/GHSA-pq7m-3gw7-gq5x)
