AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2025-11-19 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-resource-backup-logicallyairgappedbackupvault.md

Summary

Added EncryptionKeyArn property documentation with example KMS key ARN and updated terminology from 'AWS CloudFormation' to 'CloudFormation'

Security assessment

The change adds documentation about server-side encryption key usage (EncryptionKeyArn) with a concrete KMS example, which relates to security best practices for data protection. However, there's no evidence this addresses a specific security vulnerability.
