CVE-2026-41660: Admidio has Inverted 2FA Reset Authorization Check that Lets Group Leaders Strip Admin TOTP

April 29, 2026 (updated May 8, 2026)

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.
