This seems like something that might catch out unsuspecting sysadmins.
Do you think it is worth issuing an OSSN for this?

Title:
  protected property change not rejected if a subsequent rule match
  accepts them

Status in OpenStack Image Registry and Delivery Service (Glance):

Bug description:
  See initial report here: http://lists.openstack.org/pipermail
  /openstack-dev/2014-January/024861.html

  What is happening is that if there is a specific rule that would
  reject an action and a less specific rule that comes after that would
  accept the action, then the action is being accepted. It should be
  rejected.

  This is because we iterate through the property protection rules
  rather than just finding the first match. This bug does not occur when
  policies are used to determine property protections, only when roles
  are used directly.
