How to Fix CVE-2023-49080

To remediate this vulnerability, upgrade all affected Jupyter server 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-server fixed: 2.11.2 
pip install jupyter-server>=2.11.2
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-server

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-49080, inspect your installed packages using pip:

pip show jupyter-server

Analyze the terminal output to locate any version of Jupyter server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.11.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-209: Generation of Error Message Containing Sensitive Information, where the product generates an error message that includes sensitive information about its environment, users, or associated data. In Jupyter server, 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 Unhandled errors in API requests include traceback information, which can include path information. There is no known mechanism by which to trigger these errors without authentication, so the paths revealed are not considered particularly sensitive, given that the requesting user has arbitrary execution permissions already in the same environment. ### Patches jupyter-server PATCHED_VERSION no longer includes traceback information in JSON error responses. For compatibility, the traceback field is present, but always empty. ### Workarounds None
