Overview
react-dev-utils includes some utilities used by Create React App.
Affected versions of this package are vulnerable to Arbitrary Code Execution. On Windows, developers are allowed to run a local webserver for accepting various commands, including a command to launch an editor. The input to that command was not properly sanitized, allowing an attacker who can make a network request to the server (either via CSRF or by direct request) to execute arbitrary commands on the targeted system.
