Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2025-11953 is a critical-severity OS Command Injection (CWE-78) vulnerability in React-Native-Community React Native Community Cli. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2025-11953, published on 2025-11-03, is a critical OS command injection vulnerability (CWE-78) in the Metro Development Server launched by the React Native Community CLI. By default, the server binds to external interfaces and exposes an endpoint vulnerable to command injection, with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Unauthenticated network attackers can exploit the vulnerability by sending a POST request to the affected endpoint, enabling execution of arbitrary executables. On Windows, attackers gain the ability to execute arbitrary shell commands with fully controlled arguments.
A patch addressing the issue is available in the React Native Community CLI via the commit at https://github.com/react-native-community/cli/commit/15089907d1f1301b22c72d7f68846a2ef20df547. Further details on the vulnerability and mitigation are provided in the JFrog advisory at https://jfrog.com/blog/cve-2025-11953-critical-react-native-community-cli-vulnerability. The vulnerability appears in CISA's Known Exploited Vulnerabilities Catalog at https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2025-11953, signaling active real-world exploitation.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
