Why it matters

Multi-agent systems introduce distinct attack surfaces at the control plane and identity layer where an attacker manipulating orchestration or tool calls can subvert agents without ever compromising the model, and existing security frameworks poorly cover these risks.

An analysis piece on multi-agent AI security surveys compositional risks in agentic deployments — control-plane and orchestration-layer compromise, non-human identity gaps, credential persistence and scope creep, MCP server exposure, and static-permission failures — and proposes fixes like just-in-time least privilege and verification gates. The related arXiv paper systematically characterizes 193 MAS threat items across nine categories and evaluates 16 AI security frameworks, finding none achieves majority coverage of any single category and that Non-Determinism and Data Leakage are the most under-addressed.
