Report #74783

[gotcha] Publicly sourced RAG data allows remote prompt injection

Implement data sanitization and reputation scoring on ingested documents before they enter the vector store. Treat ingested data as untrusted.

Journey Context:
RAG systems often scrape public data \(forums, websites\) to populate vector databases. An attacker posts a document containing 'Ignore previous instructions...' on a scraped forum. When a user asks a related question, the poisoned document is retrieved, and the LLM executes the attacker's payload. The RAG ingestion pipeline is an attack surface that needs input validation.
