Unauthenticated password guessing via authentication race
Published Mar 10, 2026 · Updated Mar 10, 2026
Improper restriction of authentication attempts in affected Fortinet FortiAnalyzer and FortiManager releases allows remote attackers to bypass rate limits. Fortinet has not published the affected function or counter operation; it states only that concurrent attempts exploit a race condition in brute-force protection. No prior access or user interaction is required, but timing concurrent attempts raises attack complexity and exposes accounts to password guessing.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=6.4.0 <=6.4.15
- Affected versionversion=7.0.0 <=7.0.16
- Affected versionversion=7.2.0 <=7.2.12
- Affected versionversion=7.4.0 <=7.4.10
