The Author Box, Guest Author and Co-Authors for Your Posts – Molongui plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.7.7 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with author-level access and above, to perform an unauthorized action.
