Prior to 0.29.0, the Kubernetes protocol listener uses AcceptAnyClientCert in warpgate-protocol-kubernetes/src/server/client_certs.rs to accept certificates at the TLS layer and defer validation to warpgate-protocol-kubernetes/src/server/auth.rs, where authentication and lookup failures are rendered verbatim in an HTTP 500 response body. The Kubernetes application in warpgate-protocol-kubernetes/src/server/mod.rs lacks the outer request-logging wrapper used by the HTTP protocol, and failures in warpgate-protocol-kubernetes/src/server/handlers.rs can short-circuit before its inner log point. An unauthenticated network client can therefore induce failures and receive ASN.1/DER parser diagnostics or sea_orm database errors without the attempt being recorded in the gateway log. The disclosed information is limited to internal diagnostics, and no user-data, integrity, or availability impact is established.
