CVE-2025-55182Next.js (16.3.2 系)10.0✓Nパッチ即時

  • Next.js は自社運用対象の主要製品であり、cve_stats 上で kev=1 / critical=1 が計上されているため、最上位ランクとして扱っています。ただし本ダイジェストの kev_new 一覧には当該 CVE が含まれておらず、KEV 収載の時期・対象バージョン範囲は公式アドバイザリ(Next.js セキュリティアドバイザリおよび CISA KEV カタログ)で確認が必要です。
  • 実際に自社環境が影響を受けるかは、使用中のマイナーバージョンと構成(App Router / Middleware / Server Actions の利用有無等)に依存する可能性があります。

  • 🟠 ★★ 参考 CVE

  • CVE-2026-21962 — Oracle HTTP Server / WebLogic Server Proxy Plug-in (CVSS 10.0, KEV) : 不適切なアクセス制御によりデータの読み取り・改変が可能とされる。自社では Oracle ミドルウェアを運用対象としていないため直接影響は低い可能性があるが、EPSS 0.43 と高めで攻撃活動が活発化する可能性があり、委託先・関連システムでの利用有無は確認しておきたい。
  • CVE-2026-72529 — TrueConf Server (CVSS 9.8, KEV) : 4307/TCP で認証不要のスクリプト実行が可能とされる。自社の運用対象製品ではなく、該当ポートを公開したサーバも想定されないため影響は低いと考えられる。
  • CVE-2026-72530 — TrueConf Server (CVSS 9.0, KEV) : 隔離環境からのブレイクアウトによるホスト上の任意コード実行の可能性。上記同様、自社では該当製品を利用していないため影響は限定的とみられる。
  • CVE-2026-40976 — Spring Boot 4.0 / 4.1 (CVSS 9.1, KEV非該当) : 主要製品の Critical だが、attack_vector 情報が本データに含まれず is_remote が未判定のため ★★ に留めた。Spring Boot は自社運用対象に該当し得るので、実際の攻撃経路と影響コンポーネントは公式アドバイザリ(spring.io security advisories)で確認のうえ、★★★ 相当に格上げする必要がある可能性がある。

  • (参考: CVE-2026-73570 Zimbra ZCS は KEV 収載だが CVSS 8.9 かつ非主要製品のため ★ その他に分類。CVE-2026-60004 Gitea も KEV 収載だが非主要製品・CVSS 未付与で、社内 Git ホスティングに Gitea を使っている場合のみ確認が必要。)



    📝 AI 全体サマリ

  • 全体トレンド: 今週の KEV 新規収載 5 件はいずれも「認証不要または低権限での遠隔コード実行/コマンドインジェクション」に寄っており、Oracle・Zimbra・TrueConf・Gitea といったサーバサイド製品が狙われる傾向が続いている可能性があります。一方、自社の運用対象である主要 OSS 側では Spring 系(Boot 4.0/4.1・Framework 7.0)と Next.js の更新が同時期に集中し、フレームワーク層のパッチ適用計画を一度にまとめて立てられるタイミングになっています。Jenkins 2.579 も High 5 件を抱えており、CI 基盤は外部公開有無にかかわらず内部からの侵害経路になり得るため、優先度を落としすぎない運用が望ましいと考えられます。

  • 特記事項:
  • - Next.js の CVE-2025-55182 (CVSS 10.0) は本データで KEV フラグが立っている一方、kev_new には現れておらず、以前に収載された既知悪用の可能性があります。運用中バージョンが 16.3.2 未満であれば最優先で更新検討をおすすめします。

    - Spring Boot の CVE-2026-40976 は 4.0 系・4.1 系の双方に同じ CVE が計上されており、共通コンポーネント由来の可能性があります。片方だけ更新しても解消しないケースが考えられるため、両系統の稼働状況を洗い出したうえで対応するのが安全と思われます。

    - Laravel 11 系は CVE 0 件ですが eol_date が 2026-03-12 で既に期限を過ぎており、今後セキュリティ修正が提供されない可能性があります。CVE 件数だけを見ると安全に見える点に注意し、上位系統への移行計画を別途検討すべき状況とみられます。Spring Boot 4.0 系(EOL 2026-12-31)も年内に期限を迎えます。

    - Gitea の CVE-2026-60004 はリポジトリ書き込み権限を持つ攻撃者が Git hook を仕込めるとされており、社内で Gitea を自前ホストしている場合は「非主要製品」扱いでも実質的な影響が大きくなる可能性があります。運用対象台帳の確認をおすすめします。


  • PoC 検証を推奨する CVE: Next.js の CVE-2025-55182 と Spring Boot の CVE-2026-40976 について、影響有無の切り分けを検証環境で行うことを推奨します(exploit コードは作成せず、脆弱版と修正版の挙動差分の観測に留める想定)。環境構築の骨子は以下の通りです。

  • 
    # docker-compose.yml(骨子のみ。実際のバージョンは公式アドバイザリの影響範囲に合わせる)
    services:
      nextjs-vuln:
        image: node:22-bookworm
        working_dir: /app
        command: sh -c "npx --yes create-next-app@<脆弱版> app && cd app && npm run dev"
        ports: ["3000:3000"]
    
      nextjs-fixed:
        image: node:22-bookworm
        working_dir: /app
        command: sh -c "npx --yes create-next-app@16.3.2 app && cd app && npm run dev"
        ports: ["3001:3000"]
    
      springboot-vuln:
        image: eclipse-temurin:21-jre
        volumes: ["./springboot-vuln:/app"]   # 脆弱版でビルドした jar を配置
        command: java -jar /app/app.jar
        ports: ["8080:8080"]
    
      springboot-fixed:
        image: eclipse-temurin:21-jre
        volumes: ["./springboot-fixed:/app"]  # 4.0.8 / 4.1.1 でビルドした jar を配置
        command: java -jar /app/app.jar
        ports: ["8081:8080"]
    

    検証の進め方(案): ①公式アドバイザリで影響コンポーネントとバージョン範囲を確定 → ②上記の脆弱版/修正版を並べて起動 → ③該当エンドポイントへの正常系リクエストで挙動差分(レスポンス・ログ・スタックトレース)を比較 → ④自社アプリの構成が影響条件を満たすかを判定。検証はインターネットから隔離したネットワーク上で実施し、成果物は破棄する運用が望ましいと考えられます。
