In Cocos AI 0.8.2 and earlier, VerifyAttestationReportTLS in the AMD SEV-SNP verifier sets Policy.ReportData only when its caller supplies non-empty expected reportData. A relying-party integration that passes nil or empty expected reportData while relying on that value for current-session freshness can therefore accept SEV-SNP evidence unrelated to the current connection and make a trust, authorization, or application-data release decision for an unintended attestation context. This issue was fixed in Cocos AI 0.9.0 by removing the affected verifier path as part of the migration to post-handshake attestation." } ], "source": { "advisory": "GHSA-4r6g-mp48-j2rw", "discovery": "UNKNOWN" } }, "adp": [ { "references": [ { "url": "https://github.com/ultravioletrs/cocos/security/advisories/GHSA-4r6g-mp48-j2rw", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-09-22T15:05:11.173074Z", "id": "CVE-2026-92702", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-09-22T15:05:43.497Z" } } ] } }
