Title

React Router has CSRF issue in Action/Server Action Request Processing

Summary

React Router is a router for React. In @remix-run/server-runtime version prior to 2.17.3. and react-router 7.0.0 through 7.11.0, React Router (or Remix v2) is vulnerable to CSRF attacks on document POST requests to UI routes when using server-side route action handlers in Framework Mode, or when using React Server Actions in the new unstable RSC modes. There is no impact if Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>) is being used. This issue has been patched in @remix-run/server-runtime version 2.17.3 and react-router version 7.12.0.

Severity ?

6.5 (Medium)

Title

React Router vulnerable to XSS via Open Redirects

Summary

React Router is a router for React. In @remix-run/router version prior to 1.23.2. and react-router 7.0.0 through 7.11.0, React Router (and Remix v1/v2) SPA open navigation redirects originating from loaders or actions in Framework Mode, Data Mode, or the unstable RSC modes can result in unsafe URLs causing unintended javascript execution on the client. This is only an issue if you are creating redirect paths from untrusted content or via an open redirect. There is no impact if Declarative Mode (<BrowserRouter>) is being used. This issue has been patched in @remix-run/router version 1.23.2 and react-router version 7.12.0.

Title

React Router SSR XSS in ScrollRestoration

Summary

React Router is a router for React. In @remix-run/react version prior to 2.17.3. and react-router 7.0.0 through 7.11.0, a XSS vulnerability exists in in React Router's <ScrollRestoration> API in Framework Mode when using the getKey/storageKey props during Server-Side Rendering which could allow arbitrary JavaScript execution during SSR if untrusted content is used to generate the keys. There is no impact if server-side rendering in Framework Mode is disabled, or if Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>) is being used. This issue has been patched in @remix-run/react version 2.17.3 and react-router version 7.12.0.

CVE-2025-61686 (GCVE-0-2025-61686)

Vulnerability from cvelistv5 – Published: 2026-01-10 02:41 – Updated: 2026-01-10 02:41

Title

React Router has Path Traversal in File Session Storage

Summary

React Router is a router for React. In @react-router/node versions 7.0.0 through 7.9.3, @remix-run/deno prior to version 2.17.2, and @remix-run/node prior to version 2.17.2, if createFileSessionStorage() is being used from @react-router/node (or @remix-run/node/@remix-run/deno in Remix v2) with an unsigned cookie, it is possible for an attacker to cause the session to try to read/write from a location outside the specified session file directory. The success of the attack would depend on the permissions of the web server process to access those files. Read files cannot be returned directly to the attacker. Session file reads would only succeed if the file matched the expected session file format. If the file matched the session file format, the data would be populated into the server side session but not directly returned to the attacker unless the application logic returned specific session information. This issue has been patched in @react-router/node version 7.9.4, @remix-run/deno version 2.17.2, and @remix-run/node version 2.17.2.

Severity ?

9.1 (Critical)

Title

React Router has XSS Vulnerability

Summary

React Router is a router for React. In @remix-run/react versions 1.15.0 through 2.17.0. and react-router versions 7.0.0 through 7.8.2, a XSS vulnerability exists in in React Router's meta()/<Meta> APIs in Framework Mode when generating script:ld+json tags which could allow arbitrary JavaScript execution during SSR if untrusted content is used to generate the tag. There is no impact if the application is being used in Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>). This issue has been patched in @remix-run/react version 2.17.1 and react-router version 7.9.0.

Severity ?

Title

React Router has unexpected external redirect via untrusted paths

Summary

React Router is a router for React. In versions 6.0.0 through 6.30.1 and 7.0.0 through 7.9.5, 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 you are passing untrusted content into navigation paths in your application code. This issue has been patched in versions 6.30.2 and 7.9.6.

Severity ?

6.5 (Medium)

Title

React Router allows pre-render data spoofing on React-Router framework mode

Summary

React Router is a router for React. In versions on the 7.0 branch prior to version 7.5.2, it's possible to modify pre-rendered data by adding a header to the request. This allows to completely spoof its contents and modify all the values of the data object passed to the HTML. This issue has been patched in version 7.5.2.

CVE-2025-43864 (GCVE-0-2025-43864)

Vulnerability from cvelistv5 – Published: 2025-04-25 00:18 – Updated: 2025-04-25 15:18

Title

React Router allows a DoS via cache poisoning by forcing SPA mode

Summary

React Router is a router for React. Starting in version 7.2.0 and prior to version 7.5.2, it is possible to force an application to switch to SPA mode by adding a header to the request. If the application uses SSR and is forced to switch to SPA, this causes an error that completely corrupts the page. If a cache system is in place, this allows the response containing the error to be cached, resulting in a cache poisoning that strongly impacts the availability of the application. This issue has been patched in version 7.5.2.

Severity ?

7.5 (High)

CVE-2025-31137 (GCVE-0-2025-31137)

Vulnerability from cvelistv5 – Published: 2025-04-01 18:20 – Updated: 2025-04-02 15:11

Title

Remix and React Router allow URL manipulation via Host / X-Forwarded-Host headers

Summary

React Router is a multi-strategy router for React bridging the gap from React 18 to React 19. There is a vulnerability in Remix/React Router that affects all Remix 2 and React Router 7 consumers using the Express adapter. Basically, this vulnerability allows anyone to spoof the URL used in an incoming Request by putting a URL pathname in the port section of a URL that is part of a Host or X-Forwarded-Host header sent to a Remix/React Router request handler. This issue has been patched and released in Remix 2.16.3 and React Router 7.4.1.

Severity ?
