CVE-2026-21884

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.

Note

This does not impact applications if developers have disabled server-side rendering in Framework Mode, or if they are using Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>).

CVE-2026-22029

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 developers are creating redirect paths from untrusted content or via an open redirect.

Note

This does not impact applications that use Declarative Mode (<BrowserRouter>).

CVE-2026-22030

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.

Note

This does not impact applications that use Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>).

Release Notes

v7.12.0

Compare Source

Minor Changes

• Add additional layer of CSRF protection by rejecting submissions to UI routes from external origins. If you need to permit access to specific external origins, you can specify them in the react-router.config.ts config allowedActionOrigins field. (#​14708)

Patch Changes

• Fix generatePath when used with suffixed params (i.e., "/books/:id.json") (#​14269)

• Export UNSAFE_createMemoryHistory and UNSAFE_createHashHistory alongside UNSAFE_createBrowserHistory for consistency. These are not intended to be used for new apps but intended to help apps usiong unstable_HistoryRouter migrate from v6->v7 so they can adopt the newer APIs. (#​14663)

• Escape HTML in scroll restoration keys (#​14705)

• Validate redirect locations (#​14706)

• [UNSTABLE] Pass <Scripts nonce> value through to the underlying importmap script tag when using future.unstable_subResourceIntegrity (#​14675)

• [UNSTABLE] Add a new future.unstable_trailingSlashAwareDataRequests flag to provide consistent behavior of request.pathname inside middleware, loader, and action functions on document and data requests when a trailing slash is present in the browser URL. (#​14644)

  Currently, your HTTP and request pathnames would be as follows for /a/b/c and /a/b/c/

  URL /a/b/c	HTTP pathname	request pathname`
  Document	/a/b/c	/a/b/c ✅
  Data	/a/b/c.data	/a/b/c ✅

  URL /a/b/c/	HTTP pathname	request pathname`
  Document	/a/b/c/	/a/b/c/ ✅
  Data	/a/b/c.data	/a/b/c ⚠️

  With this flag enabled, these pathnames will be made consistent though a new _.data format for client-side .data requests:

  URL /a/b/c	HTTP pathname	request pathname`
  Document	/a/b/c	/a/b/c ✅
  Data	/a/b/c.data	/a/b/c ✅

  URL /a/b/c/	HTTP pathname	request pathname`
  Document	/a/b/c/	/a/b/c/ ✅
  Data	/a/b/c/_.data ⬅️	/a/b/c/ ✅

  This a bug fix but we are putting it behind an opt-in flag because it has the potential to be a "breaking bug fix" if you are relying on the URL format for any other application or caching logic.

  Enabling this flag also changes the format of client side .data requests from /_root.data to /_.data when navigating to / to align with the new format. This does not impact the request pathname which is still / in all cases.

• Preserve clientLoader.hydrate=true when using <HydratedRouter unstable_instrumentations> (#​14674)
