"The Next.js Framework on the remote host is affected by a server-side request forgery vulnerability:

  - A rewrites() or redirects() rule that builds its external destination hostname from request-controlled
    input can be pointed at an arbitrary hostname, regardless of the rule's hostname suffix. For a rewrite,
    Next.js proxies the request to that arbitrary host and serves the response from the application's origin,
    leading to Server-Side Request Forgery. A redirects() rule configured this way is vulnerable to an Open
    Redirect. (CVE-2026-64645)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
