How to Fix CVE-2024-9427

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

koji fixed: 1.35.1 
pip install koji>=1.35.1
koji fixed: 1.34.3 
pip install koji>=1.34.3
koji fixed: 1.33.2 
pip install koji>=1.33.2
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 koji

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2024-9427, inspect your installed packages using pip:

pip show koji

Analyze the terminal output to locate any version of Koji in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.35.1), your application is affected.

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

Technical Details
