Shaleen Mishra commented on CXF-7110:
-------------------------------------
What you mention is applicable for core grant types (auth code, client cred,
password, refresh token etc.) and that is implemented in
AccessTokenService.checkAudience function. There, the check is done against the
preregistered audiences of a client. However the issue i have is with one of
the extension grant types - jwt assertion grant type, where the grant handler
validates the aud parameter (which was passed in jwt body) against the current
request url.
> Inflexible jwt audience restriction validation

> Key: CXF-7110
> URL: https://issues.apache.org/jira/browse/CXF-7110
> Project: CXF
> Issue Type: Improvement
> Components: JAX-RS Security
> Affects Versions: 3.1.7
> Environment: JVM 1.7, Ubuntu 14
> Reporter: Shaleen Mishra
>
> JwtUtils.validateJwtAudienceRestriction checks the audience url matches the
> current request url (from the context). This works only during development
> but is most likely to fail because the actual url of the resource server may
> be behind the proxy or load balancer etc. e.g. The actual request is sent to
> mycomany.com/oauth and the requester sends this string in the audience
> parameter but the server actually serving the request may have a url like
> localhost:8080/oauth. So the match fails. And thanks to the static util
> function, it can not be customized easily.
