V10.2 OAuth Client

These requirements detail the responsibilities for OAuth client applications. The client can be, for example, a web server backend (often acting as a Backend For Frontend, BFF), a backend service integration, or a frontend Single Page Application (SPA, aka browser-based application).

In general, backend clients are regarded as confidential clients and frontend clients are regarded as public clients. However, native applications running on the end-user device can be regarded as confidential when using OAuth dynamic client registration.

V10.2.1 Verify that, if the code flow is used, the OAuth client has protection against browser-based …	Verify that, if the code flow is used, the OAuth client has protection against browser-based request forgery attacks, commonly known as cross-site request forgery (CSRF), which trigger token requests, either by using proof key for code exchange (PKCE) functionality or checking the 'state' parameter that was sent in the authorization request.
V10.2.2 Verify that, if the OAuth client can interact with more than one authorization server, it has a …	Verify that, if the OAuth client can interact with more than one authorization server, it has a defense against mix-up attacks. For example, it could require that the authorization server return the 'iss' parameter value and validate it in the authorization response and the token response.
V10.2.3 Verify that the OAuth client only requests the required scopes (or other authorization parameters) …	Verify that the OAuth client only requests the required scopes (or other authorization parameters) in requests to the authorization server.
