"When a user is granted access to a database with a name containing an
underscore and the underscore is not escaped then that user might also
be able to access other, similarly named, databases on the affected
system.

The problem is that the underscore is seen as a wildcard by MySQL and
therefore it is possible that an admin might accidentally GRANT a user
access to multiple databases."
