FortiManager and FortiAnalyzer, on-premises and Cloud editions, on 7.4.0-7.4.11, 7.6.0-7.6.7 or 8.0.0-8.0.1 are affected. Exploitation needs an authenticated administrator sending crafted JSON-RPC requests, so exposure depends on who has admin access and network reach to the management interface. 7.2 and teams not running these products can skip it.
Not affected if fixed-version, no-admin-access-exposed, non-affected-versions, version-7.2
