Systems Manager Run Command now supports interpolating parameters into environment variables

AWS Systems Manager (SSM) Run Command now allows customers to interpolate parameters into environment variables before command execution. Run Command allows customers to define commands that will be executed on managed instances via the SSM Agent. By interpolating parameters into environment variables, this new feature makes it easier for customers to prevent unintended command injection by handling parameters as literal strings.

Run Command is available in all AWS Commercial and AWS GovCloud (US) Regions. To get started, ensure that you are using SSM Command Documents with Schema version 2.2 and that your SSM Agent is updated to version 3.3.2746.0 or higher. To learn more about Run Command, see the Systems Manager documentation.
