The topic collection server publish needs a filter by user. Otherwise it would be possible to see other users topics in the console.

Though this is a security issue. It is considered a minor risk for two reasons:
1.) the curious attacker would need an existing meeting series ID, which is not easyily guessable. Nevertheless users that where once invited and are not invited currently could use the old MS id to get access to topics
2.) The access is not via UI, but you need JS console to gain access
