A new security vulnerability was identified with the released version of yargs-parser.
The dependency path is
react-scripts > webpack-dev-server > yargs > yargs-parser
Since react-scripts has not been updated to require the version of yargs-parser that fixes the vulnerability, the package-lock.json file needs to be updated manually to require yargs-parser version 13.1.2
See https://github.com/facebook/create-react-app/issues/9033 for a discussion on the issue with react-scripts.
