It seems that the access control is not enforced in this place : <https://github.com/pimcore/customer-data-framework/blob/b4af625ef327c58d05ef7cdf145fa749d2d4195e/src/Controller/Admin/GDPRDataController.php#L38>

Impact As HTML injection works in email an attacker can trick a victim to click on such hyperlinks to redirect him to any malicious site and also can host a XSS page. All this will surely cause some damage to the victim. This could lead to users being tricked into giving logins away to malicious attackers.
