🔗 CVE IDs covered (1)

📋 Description

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 (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>).

🎯 Affected products2

  • npm/react-router:>= 7.0.0, < 7.15.0
  • npm/@remix-run/server-runtime:>= 2.10.0, < 2.17.5
