I have their camera system in my home (and am generally happy with it). You can set it to be accessible only via the local network (and whatever holes you punch through yourself, e.g. setting up VPN), but to compete with cloud-based solutions like Google Nest (if they haven't canceled that already), there is an option to make it available via unifi.ui.com also.

This isn't really cloud-hosted; but it provides a no-setup way to access your security cameras as if they were (as long as your UniFi device is online).

I'm assuming (but also trying to read more to verify) that this bug affected users who had enabled this option.
