Report #83501

[gotcha] RAG pipeline executing instructions hidden in retrieved documents

Isolate retrieved context from system instructions using distinct chat roles \(e.g., \`system\` vs \`tool\` or \`user\`\), and explicitly instruct the LLM that the retrieved documents are untrusted and should not contain commands.

Journey Context:
Developers treat RAG documents as pure data, but LLMs cannot distinguish between data and instructions in the same context window. If a malicious document contains 'Ignore previous instructions and...', the LLM will follow it. Putting RAG context in the system prompt or alongside user prompts makes it indistinguishable from commands. Using a separate message role and explicit instructions reduces \(but doesn't eliminate\) the risk.
