Really important point, at least in the case of UMA we are clear about managing access, but even there authorization gets munged into authentication or identity. Some stems from the name, but more from misunderstanding, thanks for reminding me about this article, good time to push it.

Not only that, but many of the attacks are on assumptions about how to use OAuth to make an authentication protocol. The paper does a decent job of explaining this, and I’ve also written an article on the topic:
The same assumptions would be applied to UMA, which is also not an identity and authentication protocol.

Because UMA leverages OAuth transactions, it is vulnerable to these same attacks. However, they can be mitigated by use of existing Proof Key for Code Exchange (PKCE - pronounced "pixie") protocols. I know Justin has implemented PKCE in MITREid Connect. Not sure about other implementations.
