Which cloud threat is characterized by a flaw in one client's application exposing data from other clients in a multitenant service?

The scenario described in the question pertains to a cloud threat arising from the architecture and deployment of multitenant services. In this context, a data breach occurs when there is unauthorized access to sensitive data. Specifically, the breach is triggered by a flaw in one client's application, allowing data from other clients to be exposed.

In multitenant environments, multiple clients share the same resources and infrastructure. This architecture requires careful design to ensure that one client's data cannot inadvertently become accessible to another client. A vulnerability in the application, such as poor access controls or data isolation failure, can lead to significant security risks, exemplifying a data breach within the cloud environment.

Understanding this threat highlights the importance of robust security measures and rigorous application testing in multitenant services to protect client data from being compromised inadvertently due to another client’s vulnerabilities.
