描述

On a resumed session, "peer certificate validated" is set to false since that bit is cert by the validator flow per connection. That means any policy using mtls_authenticated evaluates to false, and can be dangerous if used as a DENY policy. The workaround is to disable session resumption in TLS.

研究方向
Investigate the SPIFFE validator implementation to understand why peer certificate validation is not triggered on session resumption. Focus on the authentication filter and TLS handshake handling in the Envoy source code. Check the relevant test files for session resumption behavior. Consider whether the fix should update the validation state on resumption or ensure the validator callback is invoked.
