  - An exposure of sensitive information to an unauthorized actor vulnerabiltiy [CWE-200] in FortiClient for
    Mac versions 7.0.0 through 7.0.5 may allow a local authenticated attacker to obtain the SSL-VPN password
    in cleartext via running a logstream for the FortiTray process in the terminal. (CVE-2022-33878)
