"The version of VMware Fusion installed on the remote macOS or Mac OS X host is 11.x prior to 11.5.5. It is, therefore,
affected by a privilege escalation vulnerability due to Improper XPC Client validation. An authenticated, local
attacker can exploit this to escalate their normal user privileges to root on the system where Fusion is installed.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
