Critical RCE in React Native CLI Exposes Dev Servers

⚠️ A critical remote-code execution vulnerability in @react-native-community/cli and its cli-server-api component lets attackers run arbitrary OS commands via the Metro development server. The flaw stems from a /open-url endpoint that forwards a supplied URL directly to the open() package and, despite console messages, the server can bind to 0.0.0.0 rather than localhost. JFrog demonstrated Windows exploitation and the issue is fixed in cli-server-api version 20.0.0; users should update or bind the server to 127.0.0.1.

Critical React Native CLI Flaw Enables Remote OS Commands

⚠ A critical vulnerability in the @react-native-community/cli ecosystem could let remote, unauthenticated attackers execute arbitrary OS commands on machines running the React Native development server. JFrog researcher Or Peles reported that the Metro dev server binds to external interfaces by default and exposes a vulnerable /open-url endpoint that passes user input to the unsafe open() call. The flaw (CVE-2025-11953, CVSS 9.8) affected versions 4.8.0–20.0.0-alpha.2 and is fixed in 20.0.0.
