React Router vulnerable to DoS via unbounded path expansion in __manifest endpoint
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| npm | react-router | >= 7.0.0, < 7.15.0 | 7.15.0 |
| npm | @remix-run/server-runtime | >= 2.10.0, < 2.17.5 | 2.17.5 |
Details
As written in the advisory (Markdown source, shown as plain text).
There exists a potential DOS attack vector in React Router Framework Mode applications (as well as Remix v2.10.0 - 2.17.4). Certain requests can be crafted to consume disproportionate resources on the server, resulting in response time degredation and/or service unavailability for end users.
> [!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>`).
