How to Fix CVE-2024-2260

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

zenml fixed: 0.56.2 
pip install zenml>=0.56.2
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 zenml

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-2260, inspect your installed packages using pip:

pip show zenml

Analyze the terminal output to locate any version of Zenml in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.56.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-384: Session Fixation, where authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. In Zenml, 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

A session fixation vulnerability exists in the zenml-io/zenml application, where JWT tokens used for user authentication are not invalidated upon logout. This flaw allows an attacker to bypass authentication mechanisms by reusing a victim's JWT token.
