AWS waf documentation change

Service: waf · 2026-05-07 · Documentation low

File: waf/latest/developerguide/waf-bot-control-components.md

Summary

Added documentation about dynamic label interpolation using ${namespace:} syntax in Bot Control for custom requests/responses, allowing single-rule handling of entire label namespaces.

Security assessment

The change documents a new WAF Bot Control feature that simplifies security configurations but doesn't address a specific vulnerability. Bot Control is a security feature, so this adds security documentation.

+  * **Custom requests and responses** – You can add custom headers to requests that you allow and you can send custom responses for requests that you block by pairing label matching with the AWS WAF custom request and response features. With dynamic label interpolation, you can use ${namespace:} syntax to resolve Bot Control label values at evaluation time. A single rule can then forward an entire label namespace as a header value, instead of requiring one rule for each label.
