The PeproDev Ultimate Invoice plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.8 via the invoicing viewer due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to view invoices for completed orders which can contain PII of users.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
