Description
CCC Attestation SIG attested-tls-poc through commit 731ca82 contains a time-of-check time-of-use vulnerability because Evidence is appraised only once during the TLS handshake, without post-handshake re-attestation. Attackers with local access to the attesting endpoint can alter workload code, data, configuration, or attached devices like GPUs while peers keep trusting the original Evidence.
