Vulnerability Title
Hatchet: Cross-tenant information disclosure in `listTasksByDAGIds`
Source: NVD (National Vulnerability Database)
Vulnerability Description
Hatchet is a platform for orchestrating background tasks, AI agents, and durable workflows at scale. Prior to 0.83.39, a missing authorization directive on the GET /api/v1/stable/dags/tasks endpoint caused Hatchet's tenant-membership check to be skipped for this route. A user authenticated to any tenant on the same Hatchet instance could query the endpoint with another tenant's UUID and a DAG UUID belonging to that tenant, and receive task metadata for that DAG. This vulnerability is fixed in 0.83.39.
