A critical alert echoes across the cybersecurity landscape as the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a stark warning regarding an actively exploited command injection vulnerability within the React Native Community CLI. Designated as CVE-2025-11953, this flaw has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalog, underscoring its immediate and severe threat to organizations and developers leveraging React Native.

CISA’s Urgent Warning and KEV Catalog Inclusion

On February 5, 2026, CISA officially listed CVE-2025-11953 in its KEV catalog. This inclusion is not merely a formality; it signifies that this particular vulnerability is not just theoretical but has been actively exploited in real-world attacks. For federal agencies, this triggers a mandate to patch affected systems by February 26, 2026, a deadline that should serve as a clear indicator of the urgency for all organizations, public and private.

Understanding Command Injection Vulnerabilities

An OS command injection flaw, such as CVE-2025-11953, allows an attacker to execute arbitrary operating system commands on the host server running the vulnerable application. In the context of the React Native Command Line Interface (CLI), this means a malicious actor could potentially gain control over the development environment or even the build process. This level of access could lead to:

• Data Exfiltration: Sensitive project data, API keys, or developer credentials could be stolen.
• Malware Injection: Attackers could inject malicious code into applications, compromising users when the application is distributed.
• System Compromise: Complete takeover of the development machine or server, leading to further网络penetratior.
• Supply Chain Attacks: Compromising the CLI could lead to malicious alterations in deployed applications, affecting end-users.

The Impact on React Native Development

React Native is a popular framework for building mobile applications using JavaScript, widely adopted for its efficiency and cross-platform capabilities. A vulnerability in its fundamental CLI tools has far-reaching implications. Developers often execute CLI commands with elevated privileges during development and build processes, making these environments prime targets for exploitation once such a flaw is present. The exploit of CVE-2025-11953 could directly impact the security posture of mobile applications built with React Native and the integrity of the development supply chain.

Remediation Actions

Given the active exploitation of CVE-2025-11953, immediate action is paramount for any organization utilizing the React Native Community CLI. The primary remediation is to update the affected component to a patched version.

• Identify Affected Versions: Determine if your projects are utilizing a vulnerable version of the React Native Community CLI. Consult official React Native documentation or community advisories for specific version information.
• Upgrade Immediately: Apply the latest security patches and update the React Native Community CLI to the recommended secure version. Always refer to the official release notes for upgrade instructions and verification.
• Implement Least Privilege: Ensure that the React Native CLI and related tools are run with the absolute minimum necessary privileges. This limits the potential damage if an exploitation occurs.
• Network Segmentation: Isolate development environments from production networks as much as possible to contain potential breaches.
• Regular Security Audits: Conduct frequent security audits of your development tooling and dependencies to identify and address vulnerabilities proactively.

Tools for Detection and Mitigation

While direct patching is the most effective solution for CVE-2025-11953, leveraging security tools can help identify its presence and enhance overall security.

Tool Name	Purpose	Link
npm audit / yarn audit	Scans project dependencies for known vulnerabilities, including CLI tools.	npm audit / yarn audit
Snyk	Identifies vulnerabilities in open-source dependencies and containers.	snyk.io
OWASP Dependency-Check	Detects publicly disclosed vulnerabilities in project dependencies.	owasp.org/www-project-dependency-check

Staying Ahead of Threats

The CVE-2025-11953 warning serves as a significant reminder that even core development tools can harbor critical vulnerabilities. Proactive security measures, continuous monitoring, and prompt patching are indispensable in safeguarding development environments and the applications they produce. Organizations must continually monitor advisories from CISA and other relevant security bodies, staying informed about newly discovered and actively exploited vulnerabilities to protect their digital assets.
