In versions 12.0.0 through 15.5.20 and 16.0.0 through 16.2.10, a\n 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. This issue has been fixed in versions 15.5.21 and 16.2.11."}], "source": {"advisory": "GHSA-p9j2-gv94-2wf4", "discovery": "UNKNOWN"}}}}
