MongoDB grants access to data and commands through role-based authorization and provides built-in roles that provide the different levels of access commonly needed in a database system. User-defined roles can also be created. Check a user's role to verify correct privileges for the function. Prerequisite: To view a user's roles, users must have the "viewUser" privilege. Connect to MongoDB. For each database in the system, identify the user's roles for the database: use <database> db.getUser("[username]") The server will return a document with the user's roles. View a role's privileges. Prerequisite: To view a user's roles, users must have the "viewUser" privilege. For each database, identify the privileges granted by a role: use <database> db.getRole( "read", { showPrivileges: true } ) The server will return a document with the "privileges" and "inheritedPrivileges" arrays. The "privileges returned" document lists the privileges directly specified by the role and excludes those privileges inherited from other roles. The "inheritedPrivileges" returned document lists all privileges granted by this role, both directly specified and inherited. If the role does not inherit from other roles, the two fields are the same. If a user has a role with inappropriate privileges, this is a finding.
