Overview
About vulnerability
When using React Router v7 [Framework Mode](https://reactrouter.com/start/modes#framework) with [Pre-rendering](https://reactrouter.com/how-to/pre-rendering) enabled, an improper neutralization of the HTTP Location header value can permit Cross-Site Scripting (XSS) in statically generated HTML files if the redirect location comes from an untrusted source.
> [!NOTE]
> This does not impact your React Router application if you are using [Declarative Mode](https://reactrouter.com/start/modes#declarative) (<BrowserRouter>) or [Data Mode](https://reactrouter.com/start/modes#data) (createBrowserRouter/<RouterProvider>).
