CVE-2026-92701Public exploitNetwork attack vector

Protected-data disclosure via missing freshness binding

Published Sep 18, 2026 · Updated Sep 18, 2026

Origin validation error in Cocos AI 0.8.2 and earlier allows remote attackers to receive protected application data via TDX aTLS. The Intel TDX verifier validates QuoteV4 Evidence without copying the current session's reportData into TdQuoteBodyPolicy.ReportData. The network-facing path requires no prior privileges or user interaction, so stale or mismatched Evidence can bind application bytes and trust decisions to an unintended attestation context.
