rack fixed: 1.5.4 
Upgrade rack to 1.5.4
rack fixed: 1.6.2 
Upgrade rack to 1.6.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for rack

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9vc2-p34x-jhxh, inspect your project dependencies for Rack:
