Unexpected SELECT permissions My user WebApp seems to have SELECT permissions on every table in every schema and I can't figure out why.


WebApp is only in the Public role.
Public doesn't own any schema.
Explicit permissions haven't been set on the tables in question
Effective permissions, as reported by SSMS, show it has SELECT permission
Figured it out. A bad script granted database-wide SELECT permissions to the user. Found it using this script:

WITH    perms_cte as
(
        select USER_NAME(p.grantee_principal_id) AS principal_name,
                dp.principal_id,
                dp.type_desc AS principal_type_desc,
                p.class_desc,
                OBJECT_NAME(p.major_id) AS object_name,
                p.permission_name,
                p.state_desc AS permission_state_desc 
        from    sys.database_permissions p
        inner   JOIN sys.database_principals dp
        on     p.grantee_principal_id = dp.principal_id
)
--users
SELECT p.principal_name,  p.principal_type_desc, p.class_desc, p.[object_name], p.permission_name, p.permission_state_desc, cast(NULL as sysname) as role_name
FROM    perms_cte p
WHERE   principal_type_desc &lt;&gt; 'DATABASE_ROLE'
UNION
--role members
SELECT rm.member_principal_name, rm.principal_type_desc, p.class_desc, p.object_name, p.permission_name, p.permission_state_desc,rm.role_name
FROM    perms_cte p
right outer JOIN (
    select role_principal_id, dp.type_desc as principal_type_desc, member_principal_id,user_name(member_principal_id) as member_principal_name,user_name(role_principal_id) as role_name--,*
    from    sys.database_role_members rm
    INNER   JOIN sys.database_principals dp
    ON     rm.member_principal_id = dp.principal_id
) rm
ON     rm.role_principal_id = p.principal_id
order by 1
