CVE-2026-108266 affecting package rust 1.96.1-2
Privasys rustls is a maintained fork of the rustls TLS library that adds RA-TLS challenge and channel-binding support. Prior to privasys-v0.8.1, the fork emitted RA-TLS challenge certificates whose quote ReportData was bound to the certificate public key and client nonce but not 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 privasys-v0.8.1.
