Easy Upload Files During Checkout <= 3.0.1 - Missing Authorization to Unauthenticated Arbitrary Attachment Deletion via 'eufdc-delete' Parameter
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.
Quick answer
Easy Upload Files During Checkout should be reviewed and updated if it matches the affected versions. The recommended fix is to apply the vendor-supported patched version or the mitigation steps below, then retest the public website with Fixnx.

How to fix it
Easy Upload Files During Checkout is affected by CVE-2026-6802, a authorization bypass issue in versions up to 3.0.1. Wordfence lists the official remediation as updating to version 3.0.2, or a newer patched version. Prioritize internet-facing WordPress sites, sites with public registration, customer portals, Elementor/page-builder surfaces, reservation or booking workflows, and admin workflows where the vulnerable feature is enabled. If immediate patching is not possible, disable the affected plugin or feature, restrict access, and monitor for exploitation until the update is installed.
- Inventory every WordPress site that has Easy Upload Files During Checkout installed, including production, staging, multisite, client, WooCommerce, marketplace, and booking environments.
- Confirm the installed Easy Upload Files During Checkout version and compare it with the affected range from the Wordfence advisory.
- Update Easy Upload Files During Checkout to version 3.0.2, or to a newer vendor-supported patched version from the official WordPress update channel.
- If the update cannot be applied immediately, disable Easy Upload Files During Checkout or the affected feature and restrict access with roles, authentication, WAF rules, or temporary route blocking.
- Review affected REST endpoints, AJAX actions, roles, capabilities, account changes, orders, bookings, payments, marketplace vendor actions, and admin actions for unauthorized activity.
- Rotate administrator sessions, API keys, webhook secrets, payment or integration tokens, and affected credentials if logs or content review suggest compromise.
- Clear WordPress, object, CDN, page-builder, security plugin, WooCommerce, and browser caches after patching so vulnerable assets or stored payloads are not served.
