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.","evidence":"cve:CVE-2026-88978","products":[{"name":{"value":"hatchet","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-88978","aliases":["CVE-2026-88978"],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":4.3,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"LOW","confidentialityImpact":"LOW"}}],"affected":[{"vendor":"hatchet-dev","product":"hatchet","versions":[{"status":"affected","version":"< 0.106.1"}]}],"modified":"2026-09-24T22:18:16.195Z","provider":"cve","references":["https://github.com/hatchet-dev/hatchet/security/advisories/GHSA-992g-9cr3-vm5x","https://github.com/hatchet-dev/hatchet/commit/15bc7923d3a8ebfeb0d88c19160dd24828921e85"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-88978","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-24T22:18:07.030391Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T22:18:16.195Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-21T15:49:12.735Z"}}},"related_cves":[{"value":"CVE-2026-88978","evidence":"/cveMetadata/cveId"}],"security_relevant":true,"severity_evidence":"/containers/cna/metrics"},"priority":{"reasons":[],"severity":"medium","linked_cves":[],"fix_available":false,"known_exploited":false,"publisher_severity":"medium"},"context_update":false,"detail_url":"/events/1949"}],"next_after":1949,"next_before":1949}
