I think it’s just a coincidence. If you don’t have a secure storage system but it’s accessible from the outside, then of course anyone could have put anything there—but that’s not a fault of UNA CMS, it’s a fault of your settings. I could be wrong, of course, and as for the UNA outage, I actually have a feeling that changes are coming that the UNA team is preparing for, and we’re just guessing or dreaming about them for now :)
