The version of Microsoft Visual Studio Code installed on the remote Windows host is prior to 1.66.2. It is, therefore, affected by privilege escalation vulnerability. An authenticated, local attacker can exploit this to escalate their privileges of an affected system.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version
