Admidio from 5.0.0 before 5.0.16 contains an authorization bypass vulnerability that allows authenticated users to export lists despite export restrictions by requesting mode=pdfl. The groups_roles_export check in modules/groups-roles/lists_show.php omits pdfl, which later runs the pdf export, letting users with list view rights download member lists as PDF files.
