Allowing any port in redirect_uri for a client

I need to allow redirect_uri to be any port on a host. For example, like “http://localhost:*/auth”. But, this exact expression doesn’t seem to work.

By simply disregarding ports and everything that follows it, if I use “http://localhost*” - this works. But the downside is that I don’t get to mention the actual endpoint. Something like “http://localhost*/auth” also doesn’t seem to work. Just wondering if there’s any right way of solving this.

Any progress on this? Would love to take the wildcard approach but don’t want someone to be able to redirect to something like http://localhost.example.com or something
