There is a critical security vulnerability in FortiOS v7.0 and FortiProxy v7.0 and v7.2 as detailed here: https://www.fortiguard.com/psirt/FG-IR-24-535
You should consider applying the mitigations as per Fortinet’s advice if you are unable to install the latest patch that resolves this issue, but patching would be the recommended approach.
It is also worth checking the IOC to confirm that you have not been impacted.
