Description
The Payment Forms for Paystack plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check and nonce verification on the export_excel function (admin_post_pff_paystack_export_excel action) in all versions up to, and including, 4.0.5. This makes it possible for authenticated attackers, with Subscriber-level access and above, to export all payment submissions for any form, including customer email addresses, amounts, transaction references and submitted metadata.
