CVE-2026-53663
A flaw was found in React Router. Insufficient Cross-Site Request Forgery CSRF checks in the framework mode allow a remote attacker to bypass these protections on PUT, PATCH, and DELETE requests. This could lead to a low integrity impact, where an attacker might be able to perform unintended...
CVE-2026-53663
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,...

CVE-2026-33244
A flaw was found in react-router. When using Framework Mode with pre-rendering enabled, an attacker can exploit improper handling of the HTTP Location header value. This can lead to Cross-Site Scripting XSS, allowing malicious scripts to be injected into statically generated HTML files if the...
React Router: Potential CSRF via PUT/PATCH/DELETE document requests
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...

Name of the Vulnerable Software and Affected Versions React Router version 7 Description Insufficient Cross-Site Request Forgery CSRF checks in Framework Mode allow bypasses when using 'PUT', 'PATCH', or 'DELETE' requests, as the checks were primarily applied to 'POST' requests. CSRF is a type of...
React Router vulnerable to Denial of Service via reflected user input in single-fetch
A DoS vulnerability exists in the React Router v7 Framework Mode, as well as Remix v2.9.0+ with Single Fetch enabled. In some scenarios the underlying serialization algorithm can become a bottleneck when encoding specific types of data into server responses. Please upgrade to React Router v7.14.0...
SUSE CVE-2026-42211
React Router is a router for React. In versions 7.0.0 through 7.14.1, when using Framework Mode, a combination of steps could potentially allow unauthorized remote code execution RCE through external requests. This attack requires the application code to have an existing prototype pollution...
SUSE CVE-2026-42342
React Router is a router for React. In versions 7.0.0 through 7.14.x of react-router and versions 2.10.0 through 2.17.4 of @remix-run/server-runtime, certain crafted requests can consume disproportionate server resources via unbounded path expansion in the manifest endpoint, resulting in response...
