The create_post function in wp-includes/class-wp-atom-server.php in WordPress before 3.4.2 does not perform a capability check, which allows remote authenticated users to bypass intended access restrictions and publish new posts by leveraging the Contributor role and using the Atom Publishing Protocol (aka AtomPub) feature.
An official patch is available. Apply the patch as soon as possible.
