However, no component of OpenShift Virtualization is known to accept protobuf messages from unauthenticated sources, hence this vulnerability is rated Moderate.\n\nRed Hat Advanced Cluster Management for Kubernetes (RHACM) includes code generated by github.com/gogo/protobuf to parse protobuf messages. However, no RHACM component is accepting  protobuf messages from unauthenticated sources and are used with a limited scope, hence this vulnerability is rated Moderate for RHACM.\n\nRed Hat Cluster Application Migration (CAM) includes code generated by github.com/gogo/protobuf to parse protobuf messages. However, no CAM component is known to accept protobuf messages from unauthenticated sources, hence this vulnerability is rated Moderate for CAM.\n\nCryostat-2 is affected as it does ship gogo/protobuf library with it\u0027s distribution but the only use for Protobuf would be the Kubernetes/OpenShift API server the operator communicates with and it should be authenticated hence it is affected with Moderate impact.",
