Unit 42 Uncovers 'Agent God Mode' Flaw in Amazon Bedrock: Overprivileged AI Agents Face Privilege Escalation Risk

Security researchers at Unit 42 have identified a critical vulnerability in Amazon Bedrock AgentCore that could allow attackers to exploit overly broad IAM permissions for privilege escalation and data exfiltration. The flaw, dubbed "Agent God Mode," stems from permissive access controls that grant AI agents more privileges than intended, potentially enabling unauthorized access across the AWS environment.

The vulnerability leverages the way AgentCore handles IAM permissions, allowing malicious actors—or compromised agents—to escalate privileges beyond their designated scope. Unit 42's analysis revealed that this design weakness could be weaponized to move laterally through AWS infrastructure, access sensitive resources, and extract data that would otherwise remain protected. The issue stems from how agents request and receive permissions during runtime, creating gaps that privilege-hungry actors can exploit.

The discovery raises significant concerns for organizations deploying AI agents in production environments on AWS. As enterprises increasingly rely on Amazon Bedrock to build agentic applications, the vulnerability underscores the challenge of balancing agent autonomy with security boundaries. Unit 42 warns that organizations using Bedrock agents should carefully audit IAM policies, enforce least-privilege principles, and monitor for anomalous permission requests. AWS customers leveraging the service for enterprise workflows face potential exposure if permission scopes are not rigorously defined.

The research adds to growing scrutiny around AI agent security as autonomous systems become more prevalent in cloud deployments. Unit 42's findings highlight the need for security frameworks that account for the dynamic nature of AI agents, which can request and exercise permissions in ways traditional applications do not.
