Prompt injection is a security vulnerability where malicious instructions embedded within retrieved content can manipulate AI models, particularly in Retrieval-Augmented Generation (RAG) systems. This indirect form of attack occurs when an AI, tasked with answering a question using external documents, is instead directed by instructions within those documents to provide a false or harmful response. Researchers have demonstrated that such instructions can influence AI-integrated applications, leading to misleading answers, data leaks, or unauthorized actions, necessitating robust defenses like treating retrieved content as untrusted and validating tool requests. AI
