CVE-2026-105812
CriticalCVSS 9.0Summary
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.
Risk Assessment
An attacker could execute arbitrary code in the context of the importing user, potentially leading to system compromise or data theft. Since the issue persists into generated source, upgrading alone is not sufficient.
Recommendation
Upgrade to version 0.3.14 or later, and re-import all agents imported with an affected version, replacing their local and deployed output artifacts.

Original NVD description (English source)
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.
