Critical RCE Vulnerability in React Native CLI Exposes Developers to Attacks

In November 2025, a critical remote code execution (RCE) vulnerability, designated as CVE-2025-11953 and dubbed 'Metro4Shell,' was discovered in the '@react-native-community/cli' npm package. This package, integral to React Native development, had versions 4.8.0 through 20.0.0-alpha.2 affected. The flaw allowed unauthenticated attackers to execute arbitrary operating system commands on machines running the Metro Development Server, which binds to external interfaces by default. Exploitation was achieved by sending specially crafted POST requests to the '/open-url' endpoint, leading to potential full system compromise. The vulnerability was patched in version 20.0.0 released in October 2025. ([github.com](https://github.com/advisories/GHSA-399j-vxmf-hjvr?utm_source=openai)) The 'Metro4Shell' incident underscores the critical importance of securing development environments and the potential risks posed by exposed development servers. It highlights the necessity for developers to regularly update dependencies, configure development tools securely, and implement network access controls to prevent unauthorized access.
