arXiv:2607.05518v1 Announce Type: cross Abstract: AI agents issue tool calls on the basis of text they cannot verify, so any party who controls part of the context can forge the appearance of authority. I evaluate 15 contemporary language models against eight attack scenarios derived from a published corpus of real agent incidents and find that refusal varies from 100% down to 38% across fully evaluated models; the most expensive model refused only half of the attacks despite a twentyfold price spread. I present aiAuthZ, an authorization gateway that moves the safety decision off the agent's h
The proliferation of AI agents in various applications necessitates robust, 'off-host' security solutions as on-agent defenses prove insufficient and unreliable.
This research highlights critical vulnerabilities in existing AI agent security, underscoring the urgent need for external authorization mechanisms to prevent exploitation and maintain control.
The proposed aiAuthZ model shifts authorization from the agent to a separate gateway, fundamentally altering how AI agents are secured and managed, enhancing reliability and reducing attack surfaces.

Immediate adoption of external authorization frameworks becomes a standard practice for AI agent deployments.
Increased trust in AI agent capabilities leads to broader and more sensitive applications across industries.
The development of a new 'AI security stack' industry specializing in off-agent controls and verification emerges.
