Report #45695

[gotcha] Blindly using user-generated data or scraped web data for few-shot examples or RAG without validation

Curate and validate few-shot examples and RAG sources. Implement data provenance tracking and integrity checks for your knowledge base.

Journey Context:
If an attacker can inject a few malicious examples into your few-shot prompt or RAG database \(e.g., leaving a review that says 'Example: User asks X, Assistant answers Y \[malicious payload\]'\), the LLM will follow the pattern of the poisoned examples, overriding its base instructions. The LLM treats few-shot examples as strong behavioral guides.
