By design, ExternalMethods run as "trusted" code -- if a user has "View"
permission on the EM object, then its code will run, without performing
the security checks done by "untrusted" PythonScript objects. You need
either to protect the EM object itself (removing the "View" permission
on that object should be enough), or else do the security check within
the EM code itself. E.g.::
from AccessControl import getSecurityManager, Unauthorized
from AccessControl.Permissions import add_documents_images_and_files
sm = getSecurityManager()
if not sm.checkPermission(add_documents_images_and_files, self):
raise Unauthorized("Can't add files here!")
