Database User with Only Create Session Privilege is able to access all data dictionary views

sudiptabhaskar

Hello Everyone,

I created user with only "Create Session" Privilege. But I can see that it is able to access all data dictionary views. Is it the default behavior?

SQL> create user bhaskar identified by *******;

User created.

SQL> grant create session to bhaskar;

Grant succeeded.

SQL> conn bhaskar

Enter password:

Connected.

User => BHASKAR has been granted the following privileges

====================================================================

       SYS PRIV => CREATE SESSION grantable => NO

SQL> select count(*) from sys.KU$_TYPE_VIEW;

 COUNT(*)

----------

        0

SQL> select count(*) from sys.v_$BH;

 COUNT(*)

----------

    12579

SQL> select file_name from sys.dba_data_files;

FILE_NAME

New database and new user. Nothing has been granted specifically.

Nothing has been granted specifically.

Prove it.

select grantee,
       owner,
       table_name,
       privilege
from dba_tab_privs
where grantee = 'PUBLIC'
;
select grantee,
       privilege
from dba_sys_privs
where grantee = 'PUBLIC'
;
