The Checkout Field Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 7.9.6. This is due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to perform an unauthorized action.
