some months ago I put up an MPLS risk analysis table during a project.
I can't publish it yet (as there are sensitive customer data in it) but will do so in the near future (anonymized).
These are the URLs I used in the reference; by them you should be able get a rough overview of the 'security aspects' of MPLS.
