Report #102337

[gotcha] The LLM only suggests actions; the user decides whether to execute them, so tool permissions don't matter.

Apply least privilege to every tool, execute in the user's OAuth context, require human-in-the-loop approval for high-impact actions, enforce authorization in downstream systems after the model proposes but before the tool runs, and log every tool call.

Journey Context:
OWASP LLM06 describes excessive agency: an LLM with broad tools, permissions, or autonomy can be hijacked by prompt injection, hallucination, or a malicious peer agent into sending emails, deleting files, or exfiltrating data. Relying on the model to 'ask permission' is fragile because the same injection that triggers the action can also suppress the confirmation. Authorization must be enforced outside the model, and irreversible actions need explicit user approval.

environment: Agentic systems, copilots, and plugins connected to email, databases, code repositories, cloud APIs, or messaging platforms. · tags: excessive-agency tool-misuse least-privilege human-in-the-loop authorization plugins llm06 · source: swarm · provenance: https://genai.owasp.org/llmrisk/llm062025-excessive-agency/
