Description OSIDB Bzimport 2026-06-02 20:02:57 UTC 
React Router is a router for React. In versions 7.7.0 through 7.13.1, when using React Router's unstable React Server Components (RSC) APIs, there is a potential client-side Cross-Site Scripting (XSS) vulnerability in the RSC redirect handling if redirects come from untrusted sources. This does not impact applications that are not using the unstable RSC APIs in React Router. This is patched in version 7.13.2.

As FreeIPA goes, we can safely waive this one, as we do not use server-side rendering and it's server components.
