CVE-2026-22030Network attack vector

Unauthorized action execution via unvalidated document POSTs

Published Jan 10, 2026 · Updated Jan 10, 2026

CSRF in React Router before 7.12.0 and Remix server runtime before 2.17.3 allows remote attackers to execute UI route actions. Document POST processing invokes server-side route actions or React Server Actions without validating the request origin. A victim must submit the cross-origin request, and only Framework Mode action handlers or unstable RSC mode are exposed.
