Prior to 0.91.1, the SNS UnsubscribeConfirmation handler in internal/integrations/ingestors/sns/sns.go calls http.Get() on payload.UnsubscribeURL after VerifyPayload() even though BuildSignature() excludes UnsubscribeURL, allowing an authenticated Hatchet tenant to replace that field in an otherwise valid AWS-signed message with an internal URL. The server-side request can reach EC2 Instance Metadata Service, internal services, and internal HTTP APIs, potentially exposing IAM credentials or network-accessible data and functionality. This issue is fixed in version 0.91.1.","evidence":"cve:CVE-2026-61681","products":[{"name":{"value":"hatchet","evidence":"/containers/cna/affected/0/product"},"prerequisites":[],"fixed_versions":[],"affected_versions":[]}],"severity":"medium","structured":{"id":"CVE-2026-61681","aliases":["CVE-2026-61681"],"metrics":[{"cvssV3_1":{"scope":"CHANGED","version":"3.1","baseScore":4.1,"attackVector":"NETWORK","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:N","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"NONE","privilegesRequired":"HIGH","confidentialityImpact":"LOW"}}],"affected":[{"vendor":"hatchet-dev","product":"hatchet","versions":[{"status":"affected","version":"< 0.91.1"}]}],"modified":"2026-09-24T22:17:06.909Z","provider":"cve","references":["https://github.com/hatchet-dev/hatchet/security/advisories/GHSA-fjwv-jf2v-j499","https://github.com/hatchet-dev/hatchet/commit/2d211bce16e5022afaf95780de82dc30e0bcba98"],"provider_metadata":{"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-61681","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-24T22:16:56.469427Z"}}}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-24T22:17:06.909Z"}}],"cna":{"orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M","dateUpdated":"2026-09-21T15:42:21.803Z"}}},"related_cves":[{"value":"CVE-2026-61681","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/1945"}],"next_after":1945,"next_before":1945}
