Critical React Native CLI Vulnerability Enables OS Command Injection  

Summary: React Native is an open source framework maintained by Meta . A critical remote code execution vulnerability in the @react-native-community/cli package, a core toolset used by React Native developers. The flaw allows unauthenticated remote attackers to execute arbitrary OS commands on machines running the React Native Metro development server.

Severity  Critical 
CVSS Score  9.8 
CVEs  CVE-2025-11953 
POC Available  Yes 
Actively Exploited  No 
Advisory Version  1.0 

Overview 

A critical remote code execution vulnerability in the @react-native-community/cli package, a core toolset used by React Native developers. The flaw allows unauthenticated remote attackers to execute arbitrary OS commands on machines running the React Native Metro development server.

The vulnerability comes from unsafe input handling in the /open-url endpoint using the insecure open() function, and a React Native CLI flaw that exposes the server to remote code execution. Immediate updates and mitigations are recommended for all using the affected package versions. 

Vulnerability Name  CVE ID  Product Affected  Severity  Affected Version 
 OS Command Injection  CVE-2025-11953  @react-native-community/cli @react-native-community/cli-server-api  Critical  @react-native-community/cli-server-api versions 4.8.0 through 20.0.0-alpha.2 

Technical Summary 

The Metro development server’s /open-url HTTP POST endpoint unsafely passes unsanitized user input (url field) as an argument to the open() function from the open NPM package which leads to OS command injection.

On Windows, the vulnerability allows arbitrary shell command execution with full control over parameters via cmd /c start command invocation. On macOS/Linux, arbitrary executables can be launched with limited parameter control. Further exploitation may lead to full RCE, but not confirmed yet. The server binds to all interfaces by default (0.0.0.0), exposing the endpoint externally to unauthenticated network attackers. 

CVE ID  Component Affected  Vulnerability Details  Impact 
CVE-2025-11953  Development Server’s /open-url Endpoint  The React Native CLI’s Metro server binds to external interfaces by default and exposes a command injection flaw, letting remote attackers send POST requests to run arbitrary executables or shell commands on Windows.  Remote OS Command Injection 

Recommendations 

  • Update to @react-native-community/cli-server-api version 20.0.0 or later immediately. 

If upgrading is not possible, 

  • Restrict the Metro server to localhost by adding the flag: –host 127.0.0.1 when starting the server. 
  • Integrate static and dynamic code analysis tools in development pipelines to detect injection risks early. 

How these kind of security flaw can cause damage?

This vulnerability poses a critical threat to React Native developers using the Metro development server due to unauthenticated RCE via network exposure. For any unauthenticated network attacker this is privilege they can weaponize the flaw and send a specially crafted POST request to the server. Then run arbitrary commands.

The attack takes a different turn when it comes to Windows and the exploitation is severe. The attackers can also execute arbitrary shell commands with fully controlled arguments, while on Linux and macOS, it can be widely used to execute arbitrary binaries with limited parameter control.

The vulnerable endpoint, /open-stack-frame, is designed to help developers open a file in their editor at a specific line number when debugging errors. This endpoint accepts POST requests with parameters such as file and lineNumber.

The incident highlight requirement for more rigorous input validation and secure-by-default configurations in developer environments.

What should organizations looks for while selecting a comprehensive tools that can provide thorough combing across their IT environment, networks, applications and cloud infrastructure.
