WatchGuard disclosed 14 Fireware OS vulnerabilities (one critical, twelve high, one medium) affecting Firebox appliances and VPN/management components; the most severe (CVE-2026-86131) permits remote code execution via BOVPN Over TLS. Fixed releases exist for affected 12.x, 2025.x, and 2026.x branches and administrators are urged to apply updates and restrict management interfaces, though WatchGuard reports no known active exploitation.
