Overview

bedrock-agentcore-starter-toolkit is an A starter toolkit for using Bedrock AgentCore

Affected versions of this package are vulnerable to Arbitrary Code Injection via the agent import functionality, which incorporates configuration values into generated Python source code without safe literal encoding. An authenticated same-account actor can supply crafted configuration values that, when a user imports and subsequently runs or deploys a Bedrock Agent, result in arbitrary code execution within the generated Python source.

Note: This is only exploitable by an authenticated actor within the same AWS account who can influence the configuration values consumed during agent import.
