Report #82193

[gotcha] LLM manipulated into calling attacker-controlled functions or arguments via indirect injection

Enforce strict schema validation on LLM-generated function arguments, whitelist allowed function calls per user session, and never execute shell commands or HTTP requests based directly on LLM output without explicit user confirmation.

Journey Context:
When an LLM has access to tools \(e.g., send\_email, execute\_code\), indirect prompt injection in a retrieved document can cause the LLM to silently invoke these tools with attacker-controlled arguments \(e.g., sending an email to the attacker\). Developers trust the LLM to only call tools when the user asks, but the LLM cannot distinguish between user intent and injected document intent.
