AWS cli medium security documentation change

Service: cli · 2026-02-28 · Security-related medium

File: cli/latest/reference/backup-gateway/update-hypervisor.md

Summary

Updated AWS CLI version, reordered parameters, modified host/ARN regex patterns, adjusted username/password documentation, added --cli-error-format

Security assessment

Host validation regex changed from ^.+$ to .+ (removing anchors), potentially allowing invalid hosts. Password regex pattern anchors removed, similar to test-hypervisor-configuration.md changes. Parameter documentation corrections could impact authentication logic.
