Free first check from your website. Connect your repo for the full answer.
Self-managed FortiManager and FortiAnalyzer appliances or VMs, plus their Cloud editions, on the versions listed by Fortinet. Exploitation needs an authenticated attacker with admin privileges sending a crafted request to the API, so risk is highest where admin credentials are shared, weak, or the management interface is reachable from untrusted networks. Fortinet reports no known exploitation (CVSS 7.2), and no virtual patch.
