Inside "Gos\Bundle\WebSocketBundle\Server\App\Dispatcher\TopicDispatcher::onPublish()", messages are arbitrarily broadcasted to the related Topic if "Gos\Bundle\WebSocketBundle\Server\App\Dispatcher\TopicDispatcher::dispatch()" does not succeed. The "dispatch()" method can be considered to not succeed if (depending on the version of the bundle) the callback defined on a topic route is misconfigured, a "Gos\Bundle\WebSocketBundle\Topic\TopicInterface" implementation is not found for the callback, a topic which also implements "Gos\Bundle\WebSocketBundle\Topic\SecuredTopicInterface" rejects the connection, or an Exception is unhandled. This can result in an unintended broadcast to the websocket server potentially with data that should be considered sensitive.
