CVE-2025-11953

React Native Community CLI

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.

Exploitation status

CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
US federal civilian agencies are required to remediate it by 2026-02-26. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
