Overview
admidio/admidio is a free open source user management system for websites of organizations and groups.
Affected versions of this package are vulnerable to Information Exposure via the members_assignment_data.php process. An attacker can infer hidden personally identifiable information such as birthdays, street addresses, cities, postal codes, and countries by performing targeted searches and analyzing which users appear in the filtered results. This is only exploitable if the attacker has role leader privileges with assign-only permissions but does not have administrator rights.
