Missing Authorization vulnerability in heoLixfy Flexible Woocommerce Checkout Field Editor allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Flexible Woocommerce Checkout Field Editor: from n/a through 2.0.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Missing authorization vulnerability in the Flexible Woocommerce Checkout Field Editor plugin allows attackers to exploit incorrectly configured access control security levels. The vulnerability likely permits unauthorized users to access or modify checkout field configurations that should be restricted to administrators. This broken access control could allow manipulation of checkout forms, potentially exposing or altering customer data entered during WooCommerce checkout.

MitigationUpdate to the latest version of the plugin (beyond 2.0.1) which should contain proper authorization checks for all sensitive endpoints and admin functionality. Review user role capabilities and restrict checkout field editor access to authorized administrative roles only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm plugin installation and version
    Navigate to WordPress admin > Plugins and locate 'Flexible Woocommerce Checkout Field Editor'. Note the installed version number displayed in the plugin list.
    Affected if The installed version is 2.0.1 or earlier.
  2. Identify active user roles
    In WordPress admin, go to Users > All Users and list all registered user roles currently present on the site.
    Affected if Non-administrator roles (such as editors, authors, subscribers, or custom roles) exist and could potentially access restricted functionality.
  3. Test admin page access with limited user
    Log in as a non-administrator user (e.g., editor or subscriber). Attempt to access the checkout field editor settings page via direct URL: /wp-admin/admin.php?page=flexible-checkout-fields-pro or similar plugin admin paths.
    Affected if The non-administrator user can access and view the plugin's admin configuration pages without being prompted for authorization.
  4. Verify checkout field API exposure
    Use a browser developer tool or curl to send a request to WooCommerce REST API endpoints related to checkout fields (e.g., /wp-json/wc/v3/flexible-checkout-fields/) while authenticated as a low-privilege user.
    Affected if The API returns checkout field configuration data or allows modifications without requiring administrator-level capabilities.
  5. Inspect capability assignments
    Check the plugin's code (if accessible via Plugins > Plugin Editor) for 'capability' or 'manage_woocommerce' definitions in the plugin files, or use a role editor plugin to review what capabilities are assigned to each user role.
    Affected if The plugin does not enforce 'manage_woocommerce' or 'administrator' capability checks before allowing access to field configuration features.

You are affected if the plugin version is 2.0.1 or earlier AND non-administrator users can access the checkout field editor settings or API without proper authorization checks.
