What the vulnerability does
The The Total Book Project plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.0 via several functions due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to perform several actions like moving/deleting/creating chapters in books that do not belong to them.

An attacker with a low-privilege account can view or alter sensitive information through the application. The vulnerability requires valid login credentials but no additional user interaction to exploit.
What an attacker can do
