Gina Cliente is storing passwords in plain text?

Hello team, in my company we are using GINA CLIENT 5.1 in windows computer, with the option of refresh the computers password by VPN. 

When the Gina Client finishe passwords reset process, it automatically store the user's password in (C:\Windows\Temp) plain Text, to then use that password to connect by VPN

Is a very high security risk, I am very disappointed.
 
PLS, how can I fixe this issue?

Thanks
