Not got much to contribute due to limited public information at this time but I did want to note that the Confidentiality and Integrity scores for this are oddly listed as Low, the Availability as None, and yet Scope is marked as Changed. My guess is that this is some sort of sandbox related escape given that if we were able to get higher permissions these scores would be a lot higher.
