Wow, it doesn't use GlideRecordSecure.

Unless I am mistaken, this would mean that any authenticated user can get any data they want if they have a minimum of read access to the record, provided they know the table, sys_id and field name, which isn't hard to get, by pasting this code into the console.

Agree!, Paul. However, you can see they have a used canRead() check. So that should be fine.  Thanks.
