Hatchet is a platform for orchestrating background tasks, AI agents, and durable workflows at scale. Prior to 0.106.1, the WorkerStatus gRPC polling path in pkg/repository/durable_events.go passes caller-supplied durable task, node, and branch identifiers to ListSatisfiedEntries without a tenant filter, allowing an authenticated tenant worker that knows another tenant's durable-task UUID to retrieve matching durable event-log records. The UUIDv4 requirement makes exploitation unlikely, and single-tenant deployments are unaffected in practice. This issue is fixed in version 0.106.1.
