The version of Next.js installed on the remote host is 12.0.0 prior to 15.5.21 or 16.0.0 prior to 16.2.11. It is, therefore, affected by multiple vulnerabilities:

- A Server-Side Request Forgery vulnerability in rewrites via an attacker-controlled destination hostname. (CVE-2026-64645)

- A Server-Side Request Forgery vulnerability in Server Actions on custom servers. This issue only affects versions 14.1.1 and later. (CVE-2026-64649)

- A Middleware / Proxy bypass in App Router applications using Turbopack and a single locale. This issue only affects versions 16.0.0 and later. (CVE-2026-64642)

- A denial of service vulnerability in App Router applications using Server Actions. This issue only affects versions 13.0.0 and later. (CVE-2026-64641)

- A denial of service vulnerability due to unbounded Server Action payloads in the Edge runtime. This issue only affects versions 13.0.0 and later. (CVE-2026-64646)

- A denial of service vulnerability in the Image Optimization API using SVGs. This issue only affects versions 15.5.0 and later. (CVE-2026-64644)

- A cache confusion of response bodies for requests with bodies. This issue only affects versions 13.0.0 and later. (CVE-2026-64648)

- A cache confusion of response bodies for requests with bodies containing invalid UTF-8 byte sequences. This issue only affects versions 13.0.0 and later. (CVE-2026-64647)

- An unauthenticated disclosure of internal Server Function endpoints. This issue only affects versions 13.0.0 and later. (CVE-2026-64643)

Note that the scanner has not attempted to exploit these issues but has instead relied only on application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Next.js is a React framework for building full-stack web applications. In versions 14.1.1 through 15.5.20
    and 16.0.0 through 16.2.10, when a Server Action forwards or redirects a request, an attacker can cause
    the server to send that outbound request to a malicious host (Server-Side Request Forgery). This requires
    the attacker's request to control Host-associated headers. In some configurations, it's also possible to
    obtain internal values that weaken middleware/proxy authorization. Applications that use Server Actions
    are affected when the incoming host header is not fixed to a trusted value. This typically occurs on
    custom servers, or on deployments not behind a proxy that pins the host. Managed hosting pins the host
    upstream and is not affected; next start and standalone output do the same from version 14.2 onward. This
    issue has been fixed in versions 15.5.21 and 16.2.11. (CVE-2026-64649)

远程主机上的 Next.js Framework 受到服务器端请求伪造漏洞的影响：

  - 服务器操作转发或重定向请求时，攻击者可导致服务器将该出站请求发送给恶意主机（服务器端请求伪造）。这需要攻击者的请求控制与主机相关的标头。在某些配置中，还可能获得削弱中间件/代理授权的内部值。（CVE-2026-64649）

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

遠端主機上的 Next.js Framework 受到伺服器端要求偽造弱點影響：

  - 當伺服器動作轉送或重新導向要求時，攻擊者可導致伺服器將該傳出要求傳送至惡意主機 （伺服器端要求偽造）。這需要攻擊者要求控制與主機相關聯的標頭。在某些組態中，也可以取得削弱中介軟體/代理授權的內部值。（CVE-2026-64649）

請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼作出判斷。

リモートホスト上の Next.js Framework は、サーバーサイドリクエスト偽造脆弱性の影響を受けます。

  - サーバーアクションがリクエストを転送またはリダイレクトするとき、攻撃者が、サーバーに悪意のあるホストにそのアウトバウンドリクエストを送信させる可能性があります(サーバー側のリクエスト偽造)。これには、ホストに関連するヘッダーを制御するために、攻撃者のリクエストが必要です。一部の構成では、ミドルウェア/プロキシ認証を弱める内部値を取得することもできます。(CVE-2026-64649)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

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

  - When a Server Action forwards or redirects a request, an attacker can cause the server to send that     outbound request to a malicious host (Server-Side Request Forgery). This requires the attacker's request     to control Host-associated headers. In some configurations, it is also possible to obtain internal values     that weaken middleware/proxy authorization. (CVE-2026-64649)

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