Vulnerability Overview

The Easy Upload Files During Checkout plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 3.0.1. This is due to missing authorization checks in the ufdc_custom_init() function, which processes the 'eufdc-delete' parameter without any nonce verification, capability check, or attachment ownership validation. This makes it possible for unauthenticated attackers to permanently delete arbitrary media library attachments from the WordPress site.

Technical Analysis

REMEDIATION: Update to version 3.0.2, or a newer patched version --- IDENTIFIER: CWE-639 (Authorization Bypass Through User-Controlled Key) 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.
