React Router SSR XSS in ScrollRestoration

Details

A XSS vulnerability exists in in React Router's `<ScrollRestoration>` API in [Framework Mode](https://reactrouter.com/start/modes#framework) 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](https://reactrouter.com/how-to/spa) in Framework Mode, or if they are using [Declarative Mode](https://reactrouter.com/start/modes#declarative) (`<BrowserRouter>`) or [Data Mode](https://reactrouter.com/start/modes#data) (`createBrowserRouter`/`<RouterProvider>`).
