Hi, Apologies up front that the subject line reads like some sort of passive-aggressive dodge ("I Am Sorry If You Feel You Have Been Abused By Us", or "I Could Tell You But Then You Would Have To Be Destroyed By Me"¹), but I didn't want to use language like THERE HAS BEEN A COMPROMISE OF YOUR DATA …because at the heart of this is a miscommunication on my part, of a situation that has existed forever. Essentially nothing has changed but it is perhaps surprising to some that things were/are the way they are. == The issue == If you are logged in to BitFolk's Grafana² to look at the graphs of your service, then you can look at the queries that the Javascript is sending, edit some of the placeholders, and look at graphs for any other BitFolk customer. This was known by me when I set up our Grafana last October/November. The possibility of logged-in users sending arbitrary queries was raised to me at the time by a couple of people, and my response to that was to set some ACLs such that only the specific queries that correspond to defined dashboards are allowed. That is, the things that you can see can also be seen by any logged in user if they make some trivial effort to do so. I thought this was acceptable because with our previous solution (Cacti), all users' graphs were visible by anyone on the Internet, and that was the case from some time in 2007 up until late last year. So in fact the current Grafana is more restrictive than Cacti was. I thought that this had been adequately communicated to you, the customer base, including to the people who had raised concerns about the Prometheus/Grafana security model. I was wrong. Conrad Wood was one of the people who kindly advised me when I was setting up Grafana/Prometheus; Conrad did warn me about this issue as did a couple of other people, and I thought that I had communicated what my solution was going to be (and that it was actually stricter than Cacti was), but I might not have. That suggests that there will be other customers who are unaware of this, and unhappy about it. == What we will do about it == I don't want customers to be unhappy, so what I will do is work on tightening up the ACLs such that logged-in users can only use the label/placeholder values that pertain to them. I will work on this as a priority but I think it will still take a couple of weeks to do. In the mean time, if you are not comfortable with the situation that any other user can craft a query to look at your CPU / bandwidth / block IO stats, please drop an email to support(a)bitfolk.com and I will block all non-admin access to your stats. That will include your own access. == Don't shoot the messenger == I appreciate that many of you probably will not care that other customers could with some minor effort look at your graphs. The fact that Conrad doesn't think it's acceptable, and repeatedly tried to tell me that (but I failed to communicate and our wires initially got crossed), probably means that there are some other customers for whom this is news and who would be unhappy about it. So I thank Conrad for bringing it to my attention again; I have adjusted my viewpoint; I will restrict it; it would not be useful for anyone to comment that they personally don't care. There will be others who care, and this is for them. (I did check with Conrad that they wanted to be named here and they indicated that would be fine. If they'd said no then I'd just have said, "a customer has brought to my attention…") Thanks for reading, and I apologise for not making the situation about visibility of stats clear throughout this long period of time.
