Summary
Hatchet: Cross-Tenant Durable Task Event Log Disclosure via Missing Authorization Check
Details

Hatchet is a platform for orchestrating background tasks, AI agents, and durable workflows at scale. Prior to 0.91.1, api-contracts/openapi/paths/v1/workflow-runs/workflow_run.yaml defines the GET /api/v1/stable/durable-tasks/{durable-task} endpoint implemented by listDurableEventLog without requiring the target tenant as a parent resource, allowing an authenticated user who obtains another tenant's durable task UUID to read that task's event log. Disclosed data can include task display names, workflow identifiers, user messages, wait conditions, branching logic, and timing information. This issue is fixed in version 0.91.1.
