AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-04-04 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-resource-bedrockagentcore-codeinterpretercustom.md

Summary

Updated IAM role ARN pattern to include additional AWS partitions (aws-cn, aws-us-gov, aws-iso variants), identical to the browser custom resource change.

Security assessment

This change expands the validation pattern for IAM role ARNs to include additional AWS partitions but does not address any security vulnerability or weakness. It's a documentation update to reflect broader AWS partition support.
