CVE-2026-108265 PUBLISHED

enclave-os-mini: RA-TLS challenge certificates were not bound to the TLS session

Assigner: GitHub_M
Reserved: 09.10.2026 Published: 09.10.2026 Updated: 09.10.2026

Enclave OS Mini is a Rust-based runtime for confidential applications inside Intel SGX enclaves. Prior to wasm-v0.40.0, the SGX runtime's RA-TLS challenge certificate path placed the certificate public-key hash and client nonce in quote ReportData but omitted a value bound to the active TLS session. An attacker who obtained an enclave TLS private key could relay a genuine quote onto another connection, causing a relying party to accept an attacker-terminated connection as the attested enclave. This issue is fixed in wasm-v0.40.0.
