よくある思い込み
HostAuthorization accepts wildcard glob patterns like '*.example.com' in permitted_hosts to authorize all subdomains.
このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。
コントラクト
- HostAuthorization treats '*.example.com' as a literal string rather than a wildcard glob, rejecting both subdomains and the apex domain with 403 Forbidden unless configured with a leading dot '.example.com'.
- HostAuthorization with leading dot '.example.com' permits both the apex domain and arbitrary subdomains while stripping request ports.
- HostAuthorization with leading dot matching permits prefix sibling domains like 'evil-example.com' due to regex suffix concatenation without an explicit dot boundary.
- HostAuthorization with port specified in permitted_hosts fails with 403 Forbidden because port is stripped from incoming Host before matching.
- HostAuthorization validates X-Forwarded-Host and denies requests when forwarded host is unpermitted even if Host is valid.
- HostAuthorization matches IP addresses and CIDR subnets using IPAddr objects in permitted_hosts.
