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. Added to CISA KEV on 2026-02-05 (federal deadline 2026-02-26).

## Steps
1. This touches infrastructure (windows). Look in terraform, ansible, cloud-init, Dockerfiles and docs for the product and version we run. If it isn't in the repo, say so and list what a human should check on the box.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.
