Description OSIDB Bzimport 2026-06-02 18:01:39 UTC 
React Router is a router for React. In versions 7.5.1 through 7.13.1, when using Framework Mode with pre-rendering enabled, improper neutralization of the HTTP `Location` header value can permit Cross-Site Scripting (XSS) in the statically generated HTML files if the redirect location comes from an untrusted source. This does not impact applications using Declarative Mode (`<BrowserRouter>`) or Data Mode (`createBrowserRouter/<RouterProvider>`). This is patched in version 7.13.2.
Comment 2 David Hanina 2026-06-03 06:48:18 UTC 
As FreeIPA goes, we can safely waive this one, as we use Declarative mode, which is not affected
