Unauthenticated login brute force via rate-limit bypass
Published Mar 10, 2026 · Updated Mar 10, 2026
Authentication rate-limit bypass in Fortinet FortiWeb allows remote attackers to make unrestricted login attempts through crafted requests. Fortinet has not disclosed the affected authentication endpoint or how crafted requests evade the attempt-limiting mechanism. No credentials are required, but credential compromise depends on sustained request capacity and the target password's complexity.
