AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2025-04-11 · Documentation low

File: AWSCloudFormation/latest/UserGuide/stacksets-orgs-manage-auto-deployment.md

Summary

Restructured documentation with updated terminology ('stacks' instead of 'stack instances'), added 'Considerations' section, and clarified automatic deployment behavior regarding account-level targets

Security assessment

Changes focus on terminology updates and operational guidance rather than addressing specific security vulnerabilities. The added consideration about automatic deployments continuing to use account-level filters warns about potential unintended deployments, but this is presented as a configuration consideration rather than a security fix.

You can enable automatic deployments and choose whether to delete or retain stacks and their associated resources when accounts are removed from target OUs. These settings can be modified anytime.
