Detailsinfo

A vulnerability classified as problematic has been found in Privasys Go. This affects an unknown functionality of the file crypto/tls of the component RA-TLS. The manipulation with an unknown input leads to a certificate validation vulnerability. CWE is classifying the issue as CWE-295. The product does not validate, or incorrectly validates, a certificate. This is going to have an impact on integrity. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-108267 since 10/09/2026. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
