ReactGuard

React2Shell scanner powered by Xint.

ReactGuard provides framework- and vulnerability-detection tooling for CVE-2025-55182 (React2Shell) across frameworks that support React Server Components. It also includes detectors for CVE-2025-55183, CVE-2025-55184, and CVE-2025-67779.

Support status

  • Next.js 14-16 and Waku 0.17-0.27: primary, validated coverage.
  • Expo server actions, React Router server actions, and generic RSC: available but experimental.
