CVE-2026-108267: CWE-346: Origin Validation Error in Privasys go
Description
Privasys Go is a maintained fork of the Go programming language that adds RA-TLS support to crypto/tls. Prior to privasys-v0.5.1-go1.26.5, challenge-mode RA-TLS certificates bound quote ReportData 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 a handshake terminated by the attacker as an attested enclave connection. This issue is fixed in privasys-v0.5.1-go1.26.5.
