Prompt injection is a significant vulnerability in applications built with frameworks like LangChain, where user input can be manipulated to override system instructions. This occurs because LLMs process all input, including user messages and system prompts, as a single stream of tokens without inherent trust boundaries. Attackers can exploit this by embedding malicious instructions within user input or even within data retrieved by the application, potentially leading to unauthorized actions if the LLM has access to tools or sensitive information. Developers can mitigate this by using chat message roles to distinguish system instructions from user input, which helps LLMs prioritize their intended directives. AI
