An authenticated and unauthorized user can access the list of potential duplicate users and see their data.
Permissions do not seem to be enforced when reaching the /admin/customermanagementframework/duplicates/list
endpoint allowing an authenticated user without the permissions to access the endpoint and query the data available there. It seems that the access control is not enforced in this place :
https://github.com/pimcore/customer-data-framework/blob/b4af625ef327c58d05ef7cdf145fa749d2d4195e/src/Controller/Admin/DuplicatesController.php#L43
In order to reproduce the issue, the following steps can be followed :
https://pimcore_instance/admin/customermanagementframework/duplicates/list
and the results will be returned to this unauthorized userAn unauthorized user can access PII data from customers without being authorized to.
