pip install curl-cffi>=0.7.0b6
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 curl-cffi

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-3vpc-4p9p-47hc, inspect your installed packages using pip:

pip show curl-cffi
