Description
Impact
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.
Patches
In 1.10.4, 2.6.1, and 3.3.0, `Gos\Bundle\WebSocketBundle\Server\App\Dispatcher\TopicDispatcher::onPublish()` has been changed to no longer broadcast an event's data if `Gos\Bundle\WebSocketBundle\Server\App\Dispatcher\TopicDispatcher::dispatch()` fails.
Workarounds
Upgrade to 1.10.4, 2.6.1, and 3.3.0
Note, the 1.x branch is considered end of support as of July 1, 2020.
