Overview
silverstripe/framework is a PHP framework forming the base for the SilverStripe CMS.
Affected versions of this package are vulnerable to Privilege Escalation. A member with the permission EDIT_PERMISSIONS and access to the "Security" section is able to re-assign themselves (or another member) to ADMIN level. CMS Fields for the member are constructed using DirectGroups instead of Groups relation which results in bypassing security logic preventing privilege escalation.
