Enterprise AI agents deployed through frameworks such as LangChain, AutoGen, and AWS Bedrock Agents are accumulating privileged access across identity systems including Microsoft Active Directory, Azure AD, Workday, and ServiceNow without triggering standard Identity Governance and Administration controls. Because IGA platforms assume every identity maps to a human HR record, agentic principals bypass provisioning reviews, access certifications, and offboarding workflows entirely, leaving orphaned, over-privileged service accounts and API keys that persist indefinitely. A documented exploitation case in ServiceNow, reported by AppOmni and covered by Silverfort and Dark Reading, demonstrates that this governance gap is now actively exploitable for agent hijacking and lateral movement across enterprise environments.
