OpenAPI Misconfiguration: Missing Operation Security Requirement

JSON
YAML

Abstract

OpenAPI 仕様は、API 操作に対して security 定義を含みません。

Explanation

API 操作では、API コンシューマーに、操作を正常に呼び出すために必要な認証および承認パラメーターを通知するためのセキュリティ要件を定義します。

security 定義を含まない操作により、攻撃者は機密性の高い API エンドポイントと対話し、明示的な権限を持つ特定のユーザーアカウントに制限する必要があるアクションを実行できるようになる可能性があります。

例 1: 次の OpenAPI 仕様は、機密性の高い操作の security 定義の設定に失敗します。さらに、グローバル security 定義がない場合、createUsers 操作は、許可および認証されていないアクセスに対して脆弱です。
