What the flaw is

React Native Community CLI contains an OS command injection vulnerability which could allow unauthenticated network attackers to send POST requests to the Metro Development Server and run arbitrary executables via a vulnerable endpoint exposed by the server. On Windows, attackers can also execute arbitrary shell commands with fully controlled arguments.

CISA's description

The Metro Development Server, which is opened by the React Native Community CLI, binds to external interfaces by default. The server exposes an endpoint that is vulnerable to OS command injection. This allows unauthenticated network attackers to send a POST request to the server and run arbitrary executables. On Windows, the attackers can also execute arbitrary shell commands with fully controlled arguments.
