The Attack Was Authorized: The Missing Security Boundary for AI Agents
The article highlights a missing security boundary for AI agents, noting that while APIs can confirm an agent’s permission, they cannot verify the user’s intended outcome. It explains that this gap can lead to unintended or malicious actions by AI systems. The author proposes using attenuated capabilities and signed receipts to create a capability‑based security layer that addresses this issue.
- ▪APIs are able to verify that an AI agent has permission to perform an action, but they cannot confirm the user’s intent behind that action.
- ▪This lack of intent verification creates a security vulnerability for agentic systems.
- ▪The proposed solution involves attenuated capabilities and signed receipts to enforce intent verification.
- ▪The approach is being implemented in a capability‑based security layer named Delegent.
- ▪The article was updated on July 23, 2026.
