PowerUserAccess in AWS environments can inadvertently grant attackers opportunities similar to those provided by AdministratorAccess, especially in complex setups. The article emphasizes the importance of adhering to the Principle of Least Privilege and advocates for regular IAM audits and the use of custom policies to mitigate risks associated with privilege escalation.

Privilege escalation risks in AWS's Bedrock AgentCore arise from its Code Interpreter tool, which allows non-agent identities to execute code and potentially gain unauthorized access to IAM roles. Without proper access controls like resource policies, these risks can lead to significant security vulnerabilities, necessitating the use of Service Control Policies for centralized management. Enhanced monitoring and auditing are also essential to prevent misuse of these powerful tools.
