  - 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. (CVE-2026-33244)

Note that Nessus relies on the presence of the package as reported by the vendor.");
