There is one available for old basic authentication which doesn't work anymore.
GitHub is full of Twitter plugins. Google this:
site:github.com twitter cakephp oauth
Or, if you feel like writing from scratch: http://code.42dh.com/oauth/ It has a small Twitter example.
This is a good intro to this kind of thing, in case you want to write your own, or use Neils plugin.
There is such a project on Google Code: http://code.google.com/p/cakephp-twitter-oauth-datasource/ though I don't know whether it still works as it was released around one year ago.
