TMA-M365-USER-CONSENT
Ensure users cannot consent to applications accessing company data
Description
Illicit consent grants let malicious OAuth apps read mail and files without a password. Compliant when no self-service permission grant policy (ManagePermissionGrantsForSelf.*) is assigned to the default user role. Requires an already-connected Microsoft Graph session: Install-Module Microsoft.Graph; Connect-MgGraph -Scopes Policy.Read.All,Directory.Read.All,RoleManagement.Read.Directory (read-only scopes). The audit throws if no session exists.
