Why it matters
Confused-deputy failures can turn prompt injection into unauthorized tool actions, making requester-aware authorization essential for agents holding privileged credentials.
NHI Mgmt Group’s guide explains how AI agents become confused deputies when untrusted instructions cause them to exercise credentials beyond the requester’s authority.
