CVE-2025-11953
Published: February 5, 2026
Official Description
React Native Community CLI contains an OS command injection vulnerability which could allow unauthenticated network attackers to send POST requests to the Metro Development Server and run arbitrary executables via a vulnerable endpoint exposed by the server. On Windows, attackers can also execute arbitrary shell commands with fully controlled arguments.
CISA KEV Advisory
React Native Community CLI OS Command Injection Vulnerability
React Native Community CLI contains an OS command injection vulnerability which could allow unauthenticated network attackers to send POST requests to the Metro Development Server and run arbitrary executables via a vulnerable endpoint exposed by the server. On Windows, attackers can also execute arbitrary shell commands with fully controlled arguments.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This critical vulnerability in React Native Community CLI allows unauthenticated attackers to inject OS commands. By sending POST requests to the Metro Development Server, arbitrary executables can be run, and on Windows, arbitrary shell commands can be executed with full control. The CVSS score of 9.8 indicates extreme severity, and its presence in CISA's KEV catalog confirms active exploitation, making immediate attention crucial.
Active exploitation of this vulnerability has been observed in the wild, as confirmed by its inclusion in CISA's KEV catalog. The attack vector is network-based with low attack complexity, meaning it is remotely exploitable without user interaction.
Organizations should apply available patches or upgrades for React Native Community CLI immediately. Restricting network access to the Metro Development Server can also help reduce exposure until a patch is applied.
Technical Analysis
CVE-2025-11953 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
CISA has added CVE-2025-11953 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
