Summary

The Checkout Field Editor for WooCommerce (Pro) plugin by Themehigh is affected up to and including 3.8.0. The ajax_remove_uploaded() function lacks a capability or ownership check (CWE-862). An unauthenticated remote attacker can delete arbitrary attachments, including those belonging to other users or posts, because the required nonce appears on public checkout pages that have a File Upload field. This can lead to loss of media and denial of service.

Description from the CNA

The Checkout Field Editor for WooCommerce (Pro) plugin for WordPress is vulnerable to unauthorized deletion of arbitrary attachments due to a missing capability/ownership check in the ajax_remove_uploaded() function in versions up to, and including, 3.8.0. The handler is registered for both wp_ajax and wp_ajax_nopriv and is gated solely by the 'file_handling_nonce' nonce, which is emitted inside the public checkout page markup (data-nonce attribute) whenever a File Upload checkout field is configured. This makes it possible for unauthenticated attackers to delete arbitrary attachments (including those belonging to other users or posts) by submitting a crafted attachment_id, which can lead to loss of important media and potential denial of service.
