npm install diagram-js-direct-editing@1.4.3
Verify Direct and Transitive Dependencies

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

npm ls diagram-js-direct-editing

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-j8r2-2x94-2q67, inspect your project dependencies using npm:

npm ls diagram-js-direct-editing
