A recent breach of TiDB, a cloud database service, has highlighted the risk of sensitive customer data being stored without either party's knowledge, leading to potential data exposure when a cloud provider is compromised.
The vulnerability or weakness
The vulnerability lies in the cloud storage practices where sensitive data might be stored without explicit awareness of both the provider and the customer, making it difficult to assess security risks.
