AI-suggested

Upgrade CyberPanel to version 3.0.5 or later, where this vulnerability is fixed. Since the vulnerability is addressed in the official fix, applying the update fully mitigates the risk.

Description

CyberPanel versions before 3.0.5 have an improper authentication vulnerability where two-factor authentication (2FA) is not enforced on API endpoints. This allows attackers who have obtained an administrator's password to bypass the Time-based One-Time Password (TOTP) requirement by deriving API tokens from the password. Consequently, attackers can perform administrative actions or create authenticated sessions without needing the second authentication factor.

Impact

An attacker who obtains an administrator's password can bypass two-factor authentication on API endpoints, gaining administrative privileges and the ability to perform sensitive operations or create authenticated sessions without the second factor. This significantly increases the risk of unauthorized access and control over the affected CyberPanel instances.

Summary

CVE-2026-88895 describes an authentication bypass vulnerability in CyberPanel prior to version 3.0.5. The product fails to enforce two-factor authentication on its API endpoints, enabling attackers with an administrator password to derive API tokens and bypass TOTP requirements. This flaw allows unauthorized administrative operations or session creation without the second factor, undermining the intended multi-factor security controls.
