CVE-2026-41659 Details
Description
Admidio is an open-source user management solution. Prior to version 5.0.9, the member assignment DataTables endpoint (members_assignment_data.php) includes hidden profile fields (BIRTHDAY, STREET, CITY, POSTCODE, COUNTRY) in its SQL search condition regardless of field visibility settings. While the JSON output correctly suppresses hidden columns via isVisible() checks, the server-side search operates at the SQL level before any visibility filtering. This allows a role leader with assign-only permissions to infer hidden PII values by observing which users appear in search results for specific values. This issue has been patched in version 5.0.9.
A vulnerability in Admidio's member assignment DataTables endpoint (members_assignment_data.php) prior to version 5.0.9 allows role leaders with assign-only permissions to infer hidden personal information. The issue arises because the SQL search condition includes concealed profile fields (BIRTHDAY, STREET, CITY, POSTCODE, COUNTRY) without regard for their visibility settings. Although the JSON output correctly omits hidden columns, the server-side search applies SQL filters before any visibility checks, enabling unauthorized access to sensitive data. This vulnerability has been patched in Admidio version 5.0.9.
Users are advised to update to Admidio version 5.0.9, where this vulnerability has been fixed.
