CVE-2026-108269

Remote Attestation TLS Clients provides multi-language utilities for verifying attested TLS connections. Prior to 0.5.0, the Rust and Go RA-TLS challenge verifiers accepted quote ReportData that was bound to the certificate public key and client nonce but not to the active TLS session before permitting application traffic. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing the clients to accept an attacker-terminated connection as the attested enclave. This issue is fixed in 0.5.0.
