  who doesn't have a right also cannot define that right as required right. That way, users who are
  editing documents on which required rights are enforced can be sure that they're not giving a
  right to a script or object that it didn't have before. A bug in the implementation of the
  enforcement of this rule means that in fact, it was possible for any user with edit right on a
  document to set programming right as required right. If then a user with programming right edited
  that document, the content of that document would gain programming right, allowing remote code
  execution.");
