CVE-2026-22572 is an authentication bypass using an alternate path or channel in the GUI of Fortinet FortiAnalyzer and FortiManager. Affected versions are FortiAnalyzer 7.6.0 through 7.6.3, 7.4.0 through 7.4.7, and 7.2.2 through 7.2.11, and FortiManager 7.6.0 through 7.6.3, 7.4.0 through 7.4.7, and 7.2.2 through 7.2.11. According to the provided content, the flaw allows an attacker who already knows a valid administrator password to bypass multifactor authentication checks by submitting multiple crafted requests through an alternate GUI path or channel. The issue is classified as CWE-288 and affects the MFA enforcement logic rather than the primary password verification step.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker in possession of a valid administrator password to authenticate to the affected management interface without completing the configured MFA challenge. This can result in unauthorized administrative access to FortiAnalyzer or FortiManager, enabling compromise of management-plane functions and any data or configuration accessible to the targeted admin account. The practical impact is a reduction of account security from password-plus-MFA to password-only for affected systems.

Mitigation

If you can’t patch tonight, do this now.

Until patching is completed, reduce exposure of the GUI management interface to trusted administrative networks only, restrict access with IP allowlists/VPN, and closely monitor authentication logs for anomalous or repeated crafted login activity. Because exploitation requires knowledge of an administrator password, immediately rotate administrator credentials, review for credential reuse, and ensure strong password hygiene. Audit MFA configuration and investigate any suspicious successful logins that did not follow expected MFA workflows.

Remediation

Patch, then assume compromise.

Upgrade FortiAnalyzer and FortiManager to a fixed release provided by Fortinet and verify installed versions against Fortinet's advisory for CVE-2026-22572 / FG-IR-26-090. Because the issue affects multiple release trains, remediation requires moving off the vulnerable versions in the 7.6.0-7.6.3, 7.4.0-7.4.7, and 7.2.2-7.2.11 ranges for the affected products. After patching, validate that MFA is enforced consistently across all GUI authentication paths.
