Why it matters
Prompt injection against RAG, memory, and tool-calling agents expands the attack surface far beyond chat responses, and defenders need to understand how a single malicious instruction can trigger unauthorized actions across connected systems.
A Medium explainer titled "Prompt Injection Is No Longer Just a Chatbot Problem" argues that as AI applications gain the ability to search documents, retain memory, call APIs, and run autonomous agent workflows, prompt injection now extends beyond chatbots to poison retrieved knowledge, corrupt long-term memory, manipulate an agent's plan, or trigger unauthorized tool calls. The piece frames prompt injection as a core security challenge across prompts, RAG, tools, memory, and agents.
