Dear Reed Arvin,

  Having  insecure  directory in PATH is configuration bug, because PATH
  is expected way to search required dynamic libraries under Windows.

  In  your  very case, user can elevate privileges by simply overwriting
  binaries of Active Perl installation.

  In  case  Active Perl doesn't let you to place binary files in Program
  Files, you may report it as Active Perl vulnerability, otherwise, it's
  vulnerability of yourself. It's common practice to set security on any
  directory you create in disk root folder.
