CVE-2025-68470: React Router has unexpected external redirect via untrusted paths

January 8, 2026 (updated January 11, 2026)

An attacker-supplied path can be crafted so that when a React Router application navigates to it via navigate(), <Link>, or redirect(), the app performs a navigation/redirect to an external URL. This is only an issue if developers pass untrusted content into navigation paths in their application code.
