Autonomous agent systems, particularly those utilizing the Model Context Protocol (MCP) and browser automation, face a new threat known as Indirect Prompt Injection (IPI). Unlike direct prompt injections, IPI occurs when an agent processes untrusted external data that contains hidden instructions designed to hijack its control flow. This vulnerability arises because LLMs treat data and instructions within the same context window, making it difficult to distinguish between developer-defined prompts and malicious ingested text, similar to how Cross-Site Scripting (XSS) affects web applications.
