{"schemaVersion":3,"id":"CVE-2026-88978","aliases":["GHSA-992g-9cr3-vm5x","GO-2026-6560"],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-09-21T15:49:12.735Z","modified":"2026-09-24T22:18:16.195Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.3,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":4.3,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
