GO-2025-3638 ServerHellos are accepted without checking TLS 1.3 downgrade canaries in github.com/refraction-networking/utls

Before version 1.7.0, utls did not implement the TLS 1.3 downgrade protection mechanism specified in RFC 8446 Section 4.1.3 when using a utls ClientHello spec. This allowed an active network adversary to downgrade TLS 1.3 connections initiated by a utls client to a lower TLS version e.g., TLS 1.2...

Protection Mechanism Failure

Overview Affected versions of this package are vulnerable to Protection Mechanism Failure in the ClientHandshake function, which handles ClientHello messages, and in particular the serverHello.random field. An attacker can downgrade the TLS connection from TLS 1.3 by removing the SupportedVersion...
