What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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.
