Sources and claim methodology

Upstream source description

CyberPanel before 3.0.5 fails to enforce two-factor authentication on API endpoints, allowing attackers to bypass TOTP requirements using password-derived tokens. Attackers who obtain an administrator's password can derive API tokens and perform administrative operations or create authenticated sessions without the second factor.
