NewCVE-2026-34381 (opens in a new tab)How to fix?
Upgrade admidio/admidio to version 5.0.8 or higher.
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 Access Control Bypass due to improper enforcement of access control in the adm_my_files directory when Apache is configured with AllowOverride None, causing .htaccess restrictions to be ignored. An attacker can access sensitive files intended for restricted roles by directly requesting the file URL, which is disclosed in the upload response JSON.
