Potentially sensitive data exposure in Symfony Web Socket Bundle

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.
