CVE-2026-56212

MEDIUM 5.1

Published 2026-06-20 · Last modified 2026-06-23

Capgo before 12.128.2 contains an authentication logic flaw: a user with permission to manage team or organization security settings can enable mandatory two-factor authentication for all team members without first enabling 2FA on their own account. The application fails to verify the initiator's 2FA status before allowing the policy change, resulting in inconsistent security enforcement, potential administrative misuse, and lockout risk for team members.
