This module adds a "Users, Groups and Permissions" report in the CMS, so that an administrator can get a quick overview of who has access to the CMS.
composer require silverstripe/securityreport
If the Subsites module is installed then an additional column will be added, allowing you to see which subsites this user can edit pages on.
To edit the permission to check for when filtering these subsites, you can update the
Member.subsite_description_permission
config to any other permission. By default this
is set to SITETREE_EDIT_ALL
.
