Why it matters
Prompt injection can redirect ChatGPT-connected RAG and agentic workflows, making layered controls and continuous adversarial testing important for protecting sensitive data.
Mindgard’s guide explains prompt-injection risks in ChatGPT, RAG, and agentic deployments, recommending layered policy enforcement, prompt hardening, continuous testing, and output filtering. The guide cites a 2024 paper reporting personal-data exfiltration from ChatGPT 4 and 4o, with additional risks involving persistent memory, but presents no new demonstration of its own.
