Introduction to FGT_100F-v7.0.6.F-build0366-FORTINET.out.zip

This critical firmware update resolves 9 documented vulnerabilities in FortiGate 100F series next-generation firewalls, specifically addressing risks identified in FortiGuard PSIRT advisory FG-IR-25-023 (April 2025). Designed for mid-sized enterprise networks, build 0366 enhances threat prevention capabilities for environments utilizing ZTNA and SD-WAN services across 50-200 endpoints.

The update targets FortiGate 100F hardware variants including FG-100F, FG-100F-BDL-250-12, and FG-101F models. System administrators managing multi-site deployments should implement this patch before August 2025 to mitigate three high-severity CVEs (7.4-8.1 CVSSv4 scores) affecting SSL-VPN and IPSec implementations.
