umbrella issues covering multiple cases of similar issues across different components in the same Dapr building blocks. None of the issues were of critical or high severity. We found a vulnerability in a 3rd-party security audit 2023 Threat model Dapr is a framework for building cloud-native applications. It consists of a runtime and a set of building blocks that allow users to move infrastructure-related tasks necessary when building microservice-based applications. The user application interacts with these components via HTTP or gRPC API endpoints. Dapr groups components into building blocks; A building block is
