Hackers exploit a critical React Native CLI flaw (CVE-2025-11953) to run remote commands and drop stealthy Rust malware, weeks before public disclosure.
Attackers are actively exploiting a critical flaw in the React Native CLI Metro server, tracked as CVE-2025-11953. The React Native CLI’s Metro dev server binds to external interfaces by default and exposes a command injection flaw. Unauthenticated attackers can send POST requests to execute arbitrary programs, and on Windows can also run shell commands with fully controlled arguments.
“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.” reads the advisory. “On Windows, the attackers can also execute arbitrary shell commands with fully controlled arguments.”
