Description

OS command injection in the Terraform hook in AWS SAM CLI before 1.166.2 might allow an actor who can influence the Terraform configuration or plan file consumed by a build to execute arbitrary commands as the build user on the host running the build via a crafted Terraform resource address. To remediate this issue, users should upgrade to version 1.166.2 or later.
