OAuth logoAs described in my last post about OAuth JAR, after it was first sent to the RFC Editor, the IESG requested an additional round of IETF feedback. I’m happy to report that, having addressed this feedback, the spec has now been sent back to the RFC Editor.

As a reminder, this specification takes the JWT Request Object from Section 6 of OpenID Connect Core (Passing Request Parameters as JWTs) and makes this functionality available for pure OAuth 2.0 applications — and does so without introducing breaking changes. This is one of a series of specifications bringing functionality originally developed for OpenID Connect to the OAuth 2.0 ecosystem. Other such specifications included OAuth 2.0 Dynamic Client Registration Protocol [RFC 7591] and OAuth 2.0 Authorization Server Metadata [RFC 8414].

The specification is available at:
