CVE-2026-108266

CriticalCVSS 9.1
Published: Translated: NVD NIST

Summary

In versions prior to privasys-v0.8.1, Privasys rustls (a fork of the rustls TLS library with RA-TLS support) 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.

Risk Assessment

Risk of accepting an unauthorized connection as a trusted enclave, potentially leading to security breaches and loss of trust in the system.

Recommendation

Update Privasys rustls to version privasys-v0.8.1 or later to ensure the quote is bound to the active TLS session.

Original NVD description (English source)

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.
