Critical RCE in React Native CLI Exposes Dev Servers

⚠️ A critical remote-code execution vulnerability in @react-native-community/cli and its cli-server-api component lets attackers run arbitrary OS commands via the Metro development server. The flaw stems from a /open-url endpoint that forwards a supplied URL directly to the open() package and, despite console messages, the server can bind to 0.0.0.0 rather than localhost. JFrog demonstrated Windows exploitation and the issue is fixed in cli-server-api version 20.0.0; users should update or bind the server to 127.0.0.1.
