Descripción
*** Pendiente de traducción *** Cocos AI is a confidential computing system for AI. 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.
