TL;DR

The OpenID Connect dynamic client registration endpoint fetches the client-supplied sector_identifier_uri without validating the URL scheme, host, or address. This lets a caller make the server issue an HTTP GET to an arbitrary URL. When open dynamic client registration is enabled it is exploitable without authentication, and otherwise any holder of a valid access token can trigger it, reaching internal services and cloud metadata endpoints. The fix validates the URI before fetching, restricting it to https and blocking private, loopback, and link-local addresses.

Who does this affect?

You are affected if you are using a version that falls within the vulnerable range.
