AWS: Cedar-Based Least-Privilege Authorization for Multi-Agent AI Chains

AWS Security Blog (July 6, 2026) detailed a pattern using the Cedar policy language to prevent authorization-scope creep as agents delegate tasks through multi-hop chains, addressing an OWASP Top 10 for Agentic Applications risk category.

Multi-agent delegation without hop-aware authorization lets an agent silently exceed the originating user's granted scope — a structural risk increasingly exploited (cf. GitLost-style leaks); Cedar-based enforcement gives builders a concrete implementation path.

Architects building multi-agent systems on AWS (Bedrock AgentCore, Lambda-orchestrated agents) should evaluate Cedar policy integration for authorization-chain enforcement.
