Vulnerability Title
Command injection in React Native Community CLI allows remote attackers to perform remote code execution by sending HTTP requests
Source: CVE Program / CVE List V5
Vulnerability 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.

7 The Metro development server started by the React Native Community CLI binds to external network interfaces by default and exposes an unauthenticated /open-url endpoint. Affected versions pass the attacker supplied url value straight to the open() helper without validating the scheme, allowing an unauthenticated attacker to launch arbitrary executables on the developer machine. On Windows the request is dispatched through cmd, which permits arbitrary shell commands with fully controlled arguments. The fix was released as a backport across several release lines, so the version number alone does not indicate whether an instance is affected, and this template probes the endpoint behaviour instead. https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2025/CVE-2025-11953.yaml POC Details
