Microsoft Entra ID Role Management Permission Grant
Id | 1ff56009-db01-4615-8211-d4fda21da02d |
Rulename | Microsoft Entra ID Role Management Permission Grant |
Description | Identifies when the Microsoft Graph RoleManagement.ReadWrite.Directory (Delegated or Application) permission is granted to a service principal. This permission allows an application to read and manage the role-based access control (RBAC) settings for your company’s directory. An adversary could use this permission to add an Microsoft Entra ID object to an Admin directory role and escalate privileges.
