"The version of Yubico YubiKey Manager installed on the remote host is prior to 1.2.6. It is, therefore,
affected by a vulnerability. Yubico ykman-gui (aka YubiKey Manager GUI) before 1.2.6 on Windows, when Edge is not used,
allows privilege escalation because browser windows can open as Administrator.
  
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
