  • CVE-2026-76504 — Cisco Catalyst SD-WAN Manager (CVSS 9.8, KEV) : 認証なしでリモートから admin 権限を取られる可能性がある URI エンコード処理の不備です。自社では Cisco SD-WAN を基本的に使っていないため影響は低いと考えられます。ただし委託先や回線事業者の管理基盤で使われている可能性もあるので、資産台帳で確認しておくと安心です。
  • CVE-2026-102489 — Zammad (CVSS 未算出, KEV) : セッション固定の脆弱性で、zammad ユーザー権限での RCE につながる可能性があります。下の CVE-2026-102490 と組み合わせると root 権限まで取られる恐れがあります。自社運用対象ではないため影響は低い見込みです。ただしヘルプデスク用にシャドー IT として導入されていないかは確認したほうがよいかもしれません。
  • CVE-2026-102490 — Zammad (CVSS 未算出, KEV) : ローカルの zammad ユーザーから root への権限昇格です。単体では前提条件がありますが、CVE-2026-102489 と組み合わせた悪用が KEV で確認されています。自社影響は上と同じく低い見込みです。
  • CVE-2026-86950 — Apple iOS / iPadOS / macOS CoreGraphics (CVSS 8.8, KEV) : 範囲外書き込みにより任意コードを実行される可能性があります。サーバ運用への影響は低いですが、社内の Mac・iPhone などの端末には影響する可能性があります。MDM で OS 更新の適用状況を確認することを推奨します。修正バージョンは Apple 公式のセキュリティアップデート情報で確認してください。

  • 全体トレンド: 今週の新規 KEV は、Zammad の連鎖悪用(RCE → root)、Cisco SD-WAN Manager の認証回避、Apple CoreGraphics の 3 系統でした。いずれも自社の主要運用対象ではありません。主要ソフトでは caddy、mediawiki(3 系列同時)、Ubuntu 24.04.5 の更新が出ています。どれも累計 CVE 統計で Critical や KEV があるため「⚠️要確認」になっていますが、多くは過去の CVE の累計である可能性があります。
  • 特記事項:
  • - caddy 2.11.7: KEV 1件と Critical 5件(CVE-2026-27590 は CVSS 9.8、CVE-2026-27587 は CVSS 9.1)を含みます。2026 年の CVE が上位にあるため、caddy を使っている環境ではリリースノートと公式アドバイザリで修正内容を確認し、早めにパッチを計画的に適用することを推奨します。KEV 1件がどの CVE か、どのバージョンで修正済みかも確認してください。

    - mediawiki 1.43 系: 最新の 1.43.10 でも still_vulnerable: 7 となっており、この系列では修正されていない CVE が残っている可能性があります。1.43 系を使っている場合は、1.46 系への移行を検討する価値があります。

    - mediawiki 1.45 系: EOL が 2026-12-31 と近づいています。使っている場合は 1.46 系(EOL 2027-07-31)への移行計画を立てることを推奨します。

    - Ubuntu 24.04.5: ポイントリリースです。KEV 40件は過去の累計の可能性が高いですが、稼働中サーバ(SecuPortal 本体を含む)で unattended-upgrades が正常に適用されているかを確認しておくとよいでしょう。

  • PoC 検証の推奨: 必須ではありません。caddy を使っている場合は、更新前後の動作確認と、該当 CVE の影響有無を確認するための検証環境の骨子を以下に示します(exploit コードは含みません)。

  • 
    # docker-compose.yml(骨子)
    services:
      caddy-old:
        image: caddy:<現行運用バージョン>
        volumes:
          - ./Caddyfile:/etc/caddy/Caddyfile:ro
        ports: ["8080:80"]
      caddy-new:
        image: caddy:2.11.7
        volumes:
          - ./Caddyfile:/etc/caddy/Caddyfile:ro
        ports: ["8081:80"]
      backend:
        image: nginxdemos/hello
    # 本番相当の Caddyfile(reverse_proxy / 認証設定など)を入れ、
    # 公式アドバイザリに書かれた影響条件の設定が使われているか、
    # 更新後に設定互換性の問題がないかを比較する
