CVE-2025-11953: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
CVE-2025-11953 is a critical OS command injection vulnerability in the Metro Development Server version 4.8.0 used by the React Native Community CLI. The server binds to external interfaces by default and exposes an endpoint that allows unauthenticated network attackers to execute arbitrary commands. On Windows systems, this enables attackers to run shell commands with fully controlled arguments. The vulnerability has a CVSS score of 9.8, indicating critical severity. No patch or official remediation information is currently available.
AI Analysis
Technical Summary
CVE-2025-11953 is an OS command injection vulnerability (CWE-78) affecting Metro Development Server version 4.8.0. The server listens on external interfaces by default and exposes an unauthenticated endpoint that allows remote attackers to execute arbitrary executables. On Windows, attackers can run arbitrary shell commands with full control over the arguments, leading to complete compromise of confidentiality, integrity, and availability. The vulnerability has a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). No patch or official remediation guidance has been provided as of the publication date.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary OS commands on affected Metro Development Server instances, resulting in full system compromise including complete loss of confidentiality, integrity, and availability. This can lead to unauthorized control over the host system and potentially further network compromise.
Mitigation Recommendations
No patch or official remediation is currently available for this vulnerability. Users should consider restricting network exposure of the Metro Development Server, especially avoiding binding to external interfaces, and apply network-level access controls to limit exposure until an official fix is released. Monitor vendor advisories for updates on remediation.
