AWS a corrigé un contournement d'authentification et deux failles de requêtes sortantes dans Loom, son plan de contrôle d'agents open source, ainsi qu'une injection de commandes dans SageMaker Unified Studio.
# Defensive check — audit an agent control plane (Loom-style) after a vendor bulletin Report, read-only: - deployed version and whether it is a fixed release - whether an identity provider is configured on every non-loopback deployment - which users and groups hold write scopes for tool servers / remote agents - outbound destinations registered for tool and agent connections: [REDACTED] - credentials the platform stores that must be rotated after upgrade Do not change configuration, rotate, restart or call any endpoint. Output the findings table only.
