A relay attack breaks attested TLS, the mechanism confidential computing uses to prove a secure cloud enclave is genuine. Formal verification found it in Meta's WhatsApp privacy system, Edgeless Systems' Contrast, Cocos AI, and three IETF draft standards, none of which a prior manual security audit caught. It's tracked as CVE-2026-33697 (CVSS 7.5), with three more related CVEs near 9.1 still in disclosure.
