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

  - h2 is a pure-Python implementation of a HTTP/2 protocol stack. Versions up to and including 4.4.0 accept
    request header blocks containing more than one Host header, and forward every Host header to the consuming
    application. Where the consumer downgrades HTTP/2 to HTTP/1.1, the resulting request carries two Host
    header lines, providing a request smuggling primitive. This issue is fixed in version 4.4.1.
    (CVE-2026-71554)

リモートのopenSUSE 16ホストには、openSUSE- SU-2026:21693-1アドバイザリに記載された脆弱性の影響を受けるパッケージがインストールされています。

    python-h2用のこの更新プログラムでは、次の問題が修正されています:

    - CVE-2026-71554:重複する「Host」ヘッダーが受け入れられ、消費するアプリケーションに転送されます。これは、リクエストスマグリングにつながる可能性があります(bsc#1274386)。

Tenable は、前述の記述ブロックを SUSE セキュリティアドバイザリから直接抽出しています。

Nessus はこ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 remote openSUSE 16 host has a package installed that is affected by a vulnerability as referenced in the openSUSE- SU-2026:21693-1 advisory.

    This update for python-h2 fixes the following issue:

    - CVE-2026-71554: duplicate `Host` headers are accepted and forwarded to consuming applications, which can     lead to       request smuggling (bsc#1274386).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
