Is this vulnerability remotely exploitable?

Yes. The affected BookController endpoints can be reached over the network, so a remote attacker can exploit the issue wherever the application is exposed.

Does an attacker need to be authenticated?

Not necessarily. Depending on how the instance is configured, exploitation may be possible without authentication or with a low-privilege account, because the core problem is insufficient authorization on the controller actions.

What is the safest general fix pattern?

Introduce strict, explicit authorization checks on all BookController operations, following a deny-by-default model and enforcing least privilege for each action (view, create, update, delete).
