There is no score here, and there will not be one

The same policy is dangerous in one deployment and harmless in another, and nothing about the document changed. The most permissive grant imaginable, running where there is nothing to reach, is a low risk; the same grant with a production database attached tomorrow is a different one. Risk is a function of the behaviour policy, the assets, the consequences and the date — and the behaviour policy is the input that does not move.

So there is no rating on anything here, no traffic light and no risk level. A policy cannot be dangerous. A deployment can.
