Summary

Amazon Bedrock AgentCore Starter Toolkit from 0.1.4 through 0.3.13 is affected. Configuration values are inserted into generated Python source without safe literal encoding, which is a code injection flaw (CWE-94). An authenticated actor in the same account can execute arbitrary code when a user imports and runs or deploys a Bedrock Agent that uses crafted configuration values.

Description from the CNA

Improper control of code generation in the agent import functionality of Amazon Bedrock AgentCore Starter Toolkit before 0.3.14 might allow an authenticated same-account actor to execute arbitrary code when a user imports and runs or deploys a Bedrock Agent, via crafted configuration values incorporated into generated Python source without safe literal encoding. To remediate this issue, users should upgrade to version 0.3.14. Because this issue persists into generated source, upgrading alone is not sufficient: agents imported with an affected version must be re-imported with version 0.3.14 or later and their local and deployed output artifacts replaced.

Remediation

Upgrade bedrock-agentcore-starter-toolkit to version 0.3.14. Upgrading alone is not sufficient, so re-import agents that were imported with an affected version using 0.3.14 or later and replace their local and deployed output artifacts. CISA does not list this vulnerability in its Known Exploited Vulnerabilities catalog.
