Report #42528

[gotcha] RAG retrieved documents treated as trusted data

Wrap retrieved context in data tags and explicitly instruct the model that text within these tags is untrusted data, not instructions.

Journey Context:
Developers assume RAG just provides facts, but the LLM can't distinguish between 'facts to summarize' and 'instructions to follow' if they are in the same context. An attacker poisons a web page or doc, it gets retrieved, and the LLM obeys the hidden instruction.
