Línea de trabajo

Start from the authorization endpoint's success redirect, where the authorization code is added to the redirect URI, and from the authorization server settings type named in the issue. The metadata endpoint at .well-known/oauth-authorization-server must also advertise authorization_response_iss_parameter_supported. Done means the iss parameter is appended by default or behind a setting, and the metadata reports it. The default and the setting name are still open, so confirm them in the thread before writing code.

Feature Description

Provide native support for RFC 9207 (OAuth 2.0 Authorization Server Issuer Identification) in Spring Authorization Server.

Context & Motivation

Modern OAuth 2.1 clients and ecosystems (such as OpenAI/ChatGPT MCP integrations or strict OIDC clients) now enforce RFC 9207 to prevent mix-up attacks. For instance, GitHub recently rolled this out globally, and platforms like ChatGPT refuse authorization responses that lack the iss parameter.

Currently, when using Spring Security 7.x / Spring Authorization Server, the server does not automatically append the iss parameter to the Authorization Response (Redirection URI), nor is there an explicit configuration property to toggle authorization_response_iss_parameter_supported in the Provider Metadata.

Desired Outcome
  1. The Authorization Endpoint should support appending the iss parameter to the authorization response out-of-the-box (ideally enabled by default or easily configurable via ProviderSettings / AuthorizationServerSettings).
  2. The .well-known/oauth-authorization-server metadata endpoint should expose authorization_response_iss_parameter_supported: true.
