AWS AWSCloudFormation medium security documentation change

Service: AWSCloudFormation · 2025-05-31 · Security-related medium

File: AWSCloudFormation/latest/TemplateReference/aws-resource-sagemaker-notebookinstance.md

Summary

Updated documentation structure to Template Reference, modified regex patterns (removed ^/$ anchors), added minimum values, and added Template Reference Guide notice

Security assessment

Removing regex anchors (^ and $) in patterns like RoleArn and others could weaken validation, potentially allowing invalid/malformed values. This impacts security by reducing strictness of input validation for critical fields like IAM roles and resource identifiers.
