thank you for taking the trouble to make me know this. im relieved im not in no mans land then! folks like you make perl understandable for beginners.
However based on a quick test of the application after a cpanm update to CGI v4.09 i still see the error/warning in my apache logs.
 CGI::param called in list context from package CGI::Session line 364, this can lead to vulnerabilities. See the warning in "Fetching the value or values of a single named parameter"
Do let me know if there is any way i can check if the issue is on my side. My detailed code is put up above.
the pertinent call is 
   my $session = $self->session();
   my $query = $self->query();
    

#clearing the session before writing new values.
 
   $session->clear();
   $session->save_param();
