pip install nova>=17.0.12
nova fixed: 18.2.2 
pip install nova>=18.2.2
nova fixed: 19.0.2 
pip install nova>=19.0.2
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 nova

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2019-14433, 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 17.0.12), your application is affected.
