## Overview

Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. Prior to 1.7.4 and 1.8.1, translateSecurityPolicyForRoute in internal/gatewayapi/securitypolicy.go dereferences a nil authorization value when a namespace-scoped tenant creates a SecurityPolicy targeting a TCPRoute and omits spec.authorization. The persistent object triggers the panic on every reconcile; recovery in message/watchutil.go keeps the process alive but unwinds the runner/runner.go handle callback, stalling controller-wide xDS and infrastructure intermediate-representation publishing until an administrator deletes the object. The data plane continues to serve the last known good configuration while publication is stalled. This issue is fixed in versions 1.7.4 and 1.8.1.
