A critical (CVSS 9.8) vulnerability, CVE-2025-11953, has been disclosed in the popular “@react-native-community/cli” NPM package, which has ~2 million weekly downloads. The flaw allows unauthenticated attackers to execute arbitrary commands on a developer’s machine via a malicious POST request to the React Native dev server.
Business Impact
This is a severe software supply chain risk. Compromising a single developer’s workstation can lead to the theft of source code, injection of malicious code into applications, and theft of cloud/platform credentials, creating a launchpad for a much larger breach.
Why It Happened
A flaw in the core codebase exposes the developer server to external network attacks, not just the local machine. This allows remote attackers to exploit the command injection vulnerability, which they normally could not reach.
Recommended Executive Action
Direct all development and application security teams to immediately update this package to the patched version (20.0.0 or higher) in all projects. This is a critical risk to your entire development pipeline.
