AWS cli documentation change

Service: cli · 2025-08-01 · Documentation low

File: cli/latest/reference/cloudfront/create-distribution.md

Summary

Added two new examples (3 and 4) demonstrating CloudFront multi-tenant distribution configurations with and without TLS certificates. Updated CLI version references from 2.27.63 to 2.28.0.

Security assessment

The changes add documentation for security-related configurations (TLS certificate usage with 'sni-only' SSL method and TLSv1.2_2021 minimum protocol) in Example 3, but there's no evidence of addressing a specific security vulnerability. Example 4 shows a less secure configuration without certificates but documents standard functionality rather than fixing an issue.
