AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2025-06-22 · Documentation low

File: AWSCloudFormation/latest/UserGuide/stacksets-update.md

Summary

Updated documentation with consistent 'StackSet' capitalization, clarified failure tolerance behavior, restructured CLI instructions with delegated admin note, and modified deployment target syntax examples

Security assessment

Changes are primarily terminology standardization (StackSet capitalization) and operational clarifications. The failure tolerance clarification improves operational safety but doesn't address a specific vulnerability. The delegated admin note reinforces existing security practices without introducing new security content.
