CVE-2026-53663

React Router: `handleDocumentRequest` CSRF check covers `POST` only; PUT/PATCH/DELETE bypass

Published Jun 22, 2026 CVSS 3.1 · 3.1 Low EPSS < 1% KEV · Not listed
Description
React Router is a router for React. From 7.12.0 until 7.15.1, certain CSRF checks in React Router v7 Framework Mode were insufficient and run on POST requests, but were bypassed on PUT/PATCH/DELETE requests. This is a low severity vulnerability because modern browser protections (CORS preflight, SameSite cookies) already block the cross-origin attack vectors that this missing CSRF check would otherwise gate. This vulnerability is fixed in 7.15.1.
