How to Fix CVE-2013-4463

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

nova fixed: 12.0.0a0 
pip install nova>=12.0.0a0
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 nova

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-4463, inspect your installed packages using pip:

pip show nova

Analyze the terminal output to locate any version of Nova in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.0.0a0), your application is affected.

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