  - React Router is a router for React. In @remix-run/react versions 1.15.0 through 2.17.0. and react-router
    versions 7.0.0 through 7.8.2, a XSS vulnerability exists in in React Router's meta()/<Meta> APIs in
    Framework Mode when generating script:ld+json tags which could allow arbitrary JavaScript execution during
    SSR if untrusted content is used to generate the tag. There is no impact if the application is being used
    in Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>). This issue has
    been patched in @remix-run/react version 2.17.1 and react-router version 7.9.0. (CVE-2025-59057)

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