Fortinet Multiple Products Authentication Bypass Using an Alternate Path or Channel Vulnerability — Fortinet FortiAnalyzer, FortiManager, FortiOS, and FortiProxy contain an authentication bypass using an alternate path or channel that could allow an attacker with a FortiCloud account and a registered device to log into other devices registered to other accounts, if FortiCloud SSO authentication is enabled on those devices. Listed in the CISA KEV catalog (added 2026-01-27) — confirmed exploited in the wild, not theoretical. FIRST EPSS puts the chance of exploitation in the next 30 days at ~86%. Treat it as real and prioritize remediation over triage.
- 0
Required action for Fortinet Multiple Products: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
