Response Actions (7 steps)

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r '@astrojs/netlify' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で `@astrojs/netlify` を grep し、稼働しているサービス・バージョンを把握する。

  2. 5
    Apply temporary workaround mitigate 
    Avoid regex metacharacters (notably `.`) in `image.remotePatterns[].pathname` values, or scope the allowed host so that unintended paths are not reachable.

    パッチが適用されるまでの応急処置として、Avoid regex metacharacters (notably `.`) in `image.remotePatterns[].pathname` values, or scope the allowed host so that unintended paths are not reachable. を実施。回避策の副作用 (機能低下) を確認した上で。

  3. 6
    Apply patch patch 
    Upgrade @astrojs/netlify to 8.1.2

    ステージング環境で 8.1.2 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスと、Step 3 で見つけた異常検知の続報チェックを含めること。

  4. 7
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 3 と同じログクエリでアラート再発が無いか継続監視。
