Self-managed FortiManager and FortiAnalyzer appliances (and the Cloud and BigData variants) on 7.6.0-7.6.7 or 8.0.0-8.0.2 are exposed when an admin profile has the JSON API (rpc-permit) enabled; it is off by default. Fortinet also lists FortiSASE-Sovereign 25.x and 26.2 as affected (26.2 already remediated, migrate from 25.x). Teams on 7.4 or 7.2, or with the JSON API disabled, can skip it.
Not affected if default-config, json-api-disabled, version-7.2, version-7.4
