Introduction to FGT_81F-v7.0.15.M-build0632-FORTINET.out.zip

This critical firmware update addresses 12 security vulnerabilities identified in FortiGate 81F series appliances under active exploitation since Q4 2024. Designed for enterprise branch offices requiring NGFW/UTM capabilities, build 0632 implements security hardening measures mandated by FortiGuard PSIRT advisory FG-IR-25-015 (March 2025).

Compatible with FortiGate 81F models (FG-81F, FG-81F-BDL-950-36), this maintenance release focuses on threat prevention system optimizations for environments utilizing SSL-VPN and SD-WAN services. System administrators managing distributed networks should prioritize installation within 30 days of release to mitigate CVE-2024-48889 session hijacking risks.
