CVE-2026-92702Public exploitNetwork attack vector

Trust bypass via unbound stale attestation evidence

Published Sep 18, 2026 · Updated Sep 18, 2026

Origin validation error in Cocos AI 0.8.2 and earlier allows remote attackers to induce trust in stale attestation evidence. VerifyAttestationReportTLS leaves Policy.ReportData unset when the expected reportData is nil, empty, or omitted, so verification does not bind Evidence to the current connection. Exposure requires a relying-party integration to use acceptance from that AMD SEV-SNP path for trust, authorization, or application-data release.
