I am not a security expert by any means, but there are several stories of excess permissions that resulted in the security breaches. The last one I actually remember was here in HN, and I think it was about a bug bounty for Facebook where a QA system could affect production. The bug bounty person "broke" production by "breaking" in the QA system.

By the way, I have no affiliation with slauth.io (just found them today as well). I just think that https://en.wikipedia.org/wiki/Principle_of_least_privilege is something good to follow in critical systems.
