AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2026-06-10 · Documentation low

File: AWSCloudFormation/latest/TemplateReference/aws-properties-bedrockagentcore-gateway-mcpgatewayconfiguration.md

Summary

Added SessionConfiguration and StreamingConfiguration properties to MCPGatewayConfiguration

Security assessment

The changes add documentation for new configuration options controlling session timeouts and response streaming capabilities. While session timeouts could be security-adjacent, there's no explicit mention of vulnerabilities, security incidents, or specific security controls. This appears to be routine feature documentation expansion.
