Service: AWSCloudFormation · 2026-06-28 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-properties-bedrockagentcore-harness-lifecycleconfiguration.md

Summary

Added documentation for session and instance lifecycle management with timeouts

Security assessment

Documents automatic termination of idle sessions and instances, which reduces attack surface. This is a security best practice but not tied to a specific vulnerability.
