SSMS Report Security Bug
To view SSMS reports there are few security roles you need to grant. In SSMS there are three types of reports.
1. Server Reports
2. Database Reports
3. SQL Server Agent Reports
To view Server Reports you need VIEW SERVER STATE permission. To view database reports, you need db_datareader permissions. However, if you have any other permissions, following is what you see.
As expected, Standard Reports are disabled but reports which were opened before are in the list!! and you can run those reports as well.
