How to fix?

Upgrade react-dev-utils to version 11.0.4 or higher.


react-dev-utils is an includes some utilities used by Create React App.

Affected versions of this package are vulnerable to Command Injection via getProcessForPort - where an input argument is concatenated into a command string to be executed. This function is typically used from react-scripts (in Create React App projects), where the usage is safe. Only when this function is manually invoked with user-provided values (ie: by custom code) is there the potential for command injection. If you're consuming it from react-scripts then this issue does not affect you.
