Not sure if this is actually desired, but data is currently showing me (a SE non-dev) mvc-mini-profiler results, including all queries that are being run against the DB (not talking about data-explorer queries of course, talking about site rendering queries).
New feature of data or a deployment whoops?
Edit:
I didn't realize that data was an open-sourced project. With that in mind, this probably isn't a security problem after all, and is in fact more likely status-bydesign.
