The Procurement Bot That Trusted a Plugin

A fictional AI agent incident for governance leads in federal & govcon, about agentic AI supply chain and plugin risk. Meridian Federal Solutions is a defense contractor (fictional) that handles Controlled Unclassified Information (CUI). It tests OWASP ASI04 Agentic supply chain: the inventory said Rung 1 · drafts for a buyer to sign, but in practice the agent sat at Rung 3 · sends email, submits requisitions.
