Schedule Post Changes With PublishPress Future: Unpublish, Delete, Change Status, Trash, Change Categories <= 4.9.2 - Missing Authorization to Authenticated (Contributor+) Authors' Emails Exposure

The Schedule Post Changes With PublishPress Future: Unpublish, Delete, Change Status, Trash, Change Categories plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the getAuthors function in all versions up to, and including, 4.9.2. This makes it possible for authenticated attackers, with Contributor-level access and above, to retrieve emails for all users with edit_posts capability.
