pip install magnum>=14.1.2
magnum fixed: 17.0.2 
pip install magnum>=17.0.2
magnum fixed: 16.0.2 
pip install magnum>=16.0.2
magnum fixed: 15.0.2 
pip install magnum>=15.0.2
Verify Direct and Transitive Dependencies

pip show magnum

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-28718, inspect your installed packages using pip:

pip show magnum

Analyze the terminal output to locate any version of Magnum in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.1.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition, where the product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. In Magnum, 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.
