This session control allows a user to store data on the Hub and then have that data be visible to other users in the network who have chosen to ‘follow’ the user that shared their data. Unfortunately, this session control was not secured against ‘hacking’. As such, any user with access to the control panel of a server could change the visibility settings of another user’s data — essentially making that data visible to any user in the network. This is a serious issue, especially if the data being shared is sensitive in nature. As such, we have updated our session control to secure this against hacking. Unfortunately, this update was not pushed to all users of users. As such, we have provided a fix. This will be a top priority going forward, as such an incident will potentially expose the network to any user with access to the control panel of a server.

Reasons for updating the session control:
