Duplicate Post, Page and Any Custom Post <= 3.5.5 - Authenticated (Contributor+) Post Disclosure via Post Duplication

The Duplicate Post, Page and Any Custom Post plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.5.5 via the 'dpp_duplicate_as_draft' function. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract potentially sensitive data from draft, scheduled (future), private, and password protected posts.
