Server-side request forgery in the OpenAPI schema processing of the agent import functionality in Amazon Bedrock AgentCore Starter Toolkit before 0.3.14 might allow an authenticated remote actor in the same AWS account to cause the environment of a user importing a Bedrock Agent to issue arbitrary outbound requests and read arbitrary local files, via crafted external reference values in the OpenAPI content associated with a Bedrock Agent action group.
To remediate this issue, users should upgrade to version 0.3.14. Note that bedrock-agentcore-starter-toolkit is deprecated. The @aws/agentcore npm CLI is the supported replacement and does not contain this issue. Migration to @aws/agentcore is the recommended long-term path.
