-
1Identify exposure identify
grep -r 'uucore' . | 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 `uucore` を grep し、稼働しているサービス・バージョンを把握する。
-
2Match against affected range verify
Confirm if version satisfies `< 0.6.0`Step 1 で見つかったバージョンが影響範囲 `< 0.6.0` に該当するか照合。本番で稼働中ならインシデント扱い。

6Apply patch patch
Upgrade uucore to 0.6.0ステージング環境で 0.6.0 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。
-
7Post-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。
