Description
The Essential Real Estate plugin for WordPress is vulnerable to Insecure Direct Object Reference via the ere_invoice_print_ajax AJAX action in all versions up to, and including, 5.3.4, due to missing validation that the requester owns the invoice referenced by the user-supplied 'invoice_id' parameter. This makes it possible for authenticated attackers, with Subscriber-level access and above who can view any invoice of their own, to view and print other users' invoices and the billing and package purchase details in them.
