CVE-2026-41660: Incorrect authorization vulnerability

Admidio is an open-source user management solution. Prior to version 5.0.9, a logic error in Admidio's two-factor authentication reset inverts the authorization check. Non-admin users cannot remove their own TOTP configuration, but they can remove other users' TOTP, including administrators. A group leader with profile edit rights on an admin account can strip that admin's 2FA. This issue has been patched in version 5.0.9.
