介绍

# React Native CLI Command Injection Demo (CVE-2025-11953)

## ⚠️ VULNERABILITY DEMONSTRATION ⚠️

**JFSA-2025-001495618** - Critical Command Injection in React Native CLI

- **CVE**: CVE-2025-11953
- **CVSS Score**: 9.8 (Critical)
- **Affected Package**: @react-native-community/cli-server-api
- **Vulnerable Versions**: [4.8.0, 20.0.0)
- **Discovery**: JFrog Security Research Team

## Vulnerability Summary

The Metro Development Server, which is opened by the React Native CLI, binds to external interfaces by default. The server exposes an endpoint (`/open-url`) that is vulnerable to OS command injection. This allows unauthenticated network attackers to send a POST request to the server and run arbitrary executables.

### Impact
- **Remote Code Execution (RCE)**
- **Command Injection**
- **No Authentication Required**
- **Network Accessible**
