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.","state":0,"publishedAt":"2026-09-18T17:02:48.37+00:00","modifiedAt":"2026-10-13T20:08:52.222+00:00","affected":[{"ecosystem":"Vendor product","name":"cocos","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ultravioletrs\",\n                    \"product\": \"cocos\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.9.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/ultravioletrs/cocos/security/advisories/GHSA-4r6g-mp48-j2rw","https://github.com/ultravioletrs/cocos/pull/582","https://github.com/ultravioletrs/cocos/commit/80bf813c48300f02259b338b91f844c71be582ea","https://github.com/ultravioletrs/cocos/releases/tag/v0.9.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92702","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92702","identifiers":["CVE-2026-92702"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
