HIGH 7.5

GHSA-8x6r-g9mw-2r78

React Router vulnerable to DoS via unbounded path expansion in __manifest endpoint

Quick fix

GHSA-8x6r-g9mw-2r78 — react-router: upgrade to the fixed version with the command below.

npm install react-router@7.15.0

Details

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>`).
