Detailsinfo

A vulnerability classified as problematic was found in Hatchet-dev Hatchet up to 0.106.0. This vulnerability affects the function ListSatisfiedEntries of the file pkg/repository/durable_events.go of the component WorkerStatus gRPC polling path. The manipulation of the argument durable_task/node/branch with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-88978 since 09/10/2026. The exploitation appears to be easy. The attack can be initiated remotely.
