create-react-app: Missing Origin Validation in react-scripts@2.1.2

Is this a bug report?

Yes, NPM reports 1 high severity vulnerability when running npx create-react-app my-app. Not sure why I can’t find a bug report already about this issue. Sorry if it has already been reported.

According to npm audit, the webpack-dev-server dependency has to be upgraded to >=3.1.11.

Success! Created my-app at /Users/sunknudsen/tmp/my-app
Inside that directory, you can run several commands:

  npm start
    Starts the development server.

  npm run build
    Bundles the app into static files for production.

  npm test
    Starts the test runner.

  npm run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd my-app
  npm start

Happy hacking!
