Authentication bypass via replayed 2FA request
Published Apr 14, 2026 · Updated Apr 14, 2026
Improper authentication in Fortinet FortiSOAR products 7.5.0 through 7.5.2 and 7.6.0 through 7.6.3 allows attackers to bypass 2FA. The authentication flow accepts a previously captured 2FA request as valid when it is replayed before the associated token expires. Exploitation requires interception and decryption of authentication traffic, a victim's 2FA interaction, and precise replay timing; successful replay bypasses the second authentication factor.
