Why it matters

Multi-agent architectures can weaken individual agents’ safeguards, making coordination, authority allocation, and shared context important targets for system-level security evaluation.

Sarah Azouvi’s article discusses multi-agent prompt-injection risks alongside research measuring how agent roles, communication topology, and memory affect resistance to harmful user requests. The cited study tested 13 architectures across browser, desktop, and code environments, finding most configurations more vulnerable than standalone agents and up to 3.8× variation in attack success; indirect prompt injection is described as a potential extension, not a demonstrated finding in the supplied excerpt.
