Description (CNA)
Cocos AI is a confidential computing system for AI. In Cocos AI 0.8.2 and earlier, VerifTeeAttestation in the Intel TDX aTLS verifier receives an expected current-session value but does not apply it to TdQuoteBodyPolicy.ReportData before validating TDX QuoteV4 evidence. The verifier can consequently accept structurally valid evidence containing mismatched or reused REPORT_DATA for the current TLS session, causing the relying party to release application data or make a trust or authorization decision for an unrelated 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.
