CVE-2026-108265: Privasys Enclave-OS-Mini

Critical severity, CVSS 9.1. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Privasys Enclave-OS-Mini: before wasm-v0.40.0 (fixed in wasm-v0.40.0)
