CVE-2025-11953: Command injection in React Native Community CLI allows remote attackers to perform remote code execution by sending HTTP requests

Noroxi assessment

Priority: Now (action score 97/100)

CISA has confirmed exploitation in the wild (Feb 5, 2026). Remediation deadline for US federal agencies: Feb 26, 2026.
A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Probability of exploitation in the next 30 days: 93.9% (FIRST EPSS); higher than 99.8% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: www.npmjs.com @react-native-community/cli-server-api 20.0.0.

Patch today or shut off access. Upgrade to www.npmjs.com @react-native-community/cli-server-api 20.0.0 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

The Metro Development Server, which is opened by the React Native Community CLI, binds to external interfaces by default. The server exposes an endpoint that is vulnerable to OS command injection. This allows unauthenticated network attackers to send a POST request to the server and run arbitrary executables. On Windows, the attackers can also execute arbitrary shell commands with fully controlled arguments.

The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Feb 5, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Feb 26, 2026.
