A remote authenticated third party can trigger arbitrary code execution in Amazon Virtual Engineering Workbench's publishing component by submitting a crafted CloudFormation template body containing template engine directives through the product versioning API. This executes with the permissions of the publishing Lambda's IAM role, potentially accessing data and resources across all tenant projects.
What to do: Redeploy from the latest version of awslabs/virtual-engineering-workbench.
