QTINeon has unauthenticated relay-to-host amplification via unbounded RECONNECT_REQUEST forwarding

ImpactThe relay's reconnect handler forwards every RECONNECTREQUEST to the host without deduplication or a size cap on the pendingReconnects map, unlike the connect flow which guards against this with maxPendingConnections. An unauthenticated attacker who knows a valid session ID can send...
