vitest 4.1.0 → 4.1.2 調査レポート

変更内容

v4.1.1

• (実験的) matchesTags API、experimental.vcsProvider の追加
• vi.mocked() の型回帰修正、ソフトアサーション修正、sinon-chai API修正など多数のバグ修正

v4.1.2

• CVE対応: 依存パッケージ flatted のバージョンアップ
  • CVE-2026-32141 (DoS): parse() の無制限再帰によるスタックオーバーフロー
  • CVE-2026-33228 (プロトタイプ汚染): Array.prototype 汚染の可能性
• setupFiles の解決パス修正、mock/unmock の順序保証、coverageConfigDefaults 修正

セキュリティ

• flatted の2件のCVE修正が含まれるため、アップグレード推奨
• vitest は開発依存のため本番環境への直接的リスクは低いが、テスト環境のセキュリティ向上に寄与

破壊的変更

• なし（パッチリリース）

CI状況

• CIは失敗中: @vitest/coverage-v8 が 4.1.0 のままで peer dependency 競合が発生
• 対応: PR chore(deps-dev): bump @vitest/coverage-v8 from 4.1.0 to 4.1.2 #225 (@vitest/coverage-v8 4.1.0 → 4.1.2) と合わせてマージする必要あり

結論

パッケージ自体は安全。PR #225 と統合してマージすること。
