Please, yes. At a previous job, a department used a Windows accounting app that had a machine-level ODBC connection with the database credentials saved in it. A user figured out you could use Microsoft Query to pull data from the ODBC connection into Excel. This worked well until she accidentally deleted 90% of the vendor records from the database while trying to filter some data. I couldn't even really be upset at the user, a bunch of dumb product design decisions had to align like swiss cheese for this to happen.
