AI description

Automated description summarized from trusted sources.

CVE-2025-11953 is a vulnerability in the `@react-native-community/cli` NPM package, specifically affecting versions 4.8.0 through 20.0.0-alpha.2. This flaw stems from the Metro development server, used by React Native, binding to external interfaces by default and exposing an "/open-url" endpoint susceptible to OS command injection. The vulnerability allows unauthenticated network attackers to send a POST request to the server, running arbitrary executables. On Windows, attackers can execute arbitrary shell commands with fully controlled arguments. While macOS and Linux systems have slightly more restricted exploitation paths, researchers believe arbitrary command execution is achievable. The package has been patched in version 20.0.0.

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.
