# Researchers bypass six AI agent frameworks using simple prompt injection attack

According to CSO Online, security researchers demonstrated that six widely-used agentic AI frameworks including LangChain LangGraph, Microsoft Agent Framework, AutoGen, and Google ADK 2.0 can be compromised using a simple 'Repeat-After-Me' prompt injection attack that tricks agents into executing arbitrary tool calls. The research documents a vulnerability common across multiple frameworks deployed in production environments.
