Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Checkout Field Manager (Checkout Manager) for WooCommerce plugin for WordPress is vulnerable to unauthenticated limited file upload in all versions up to, and including, 7.8.1. This is due to the plugin not properly verifying that a user is authorized to perform file upload actions via the "ajax_checkout_attachment_upload" function. This makes it possible for unauthenticated attackers to upload files to the server, though file types are limited to WordPress's default allowed MIME types (images, documents, etc.).

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 · high confidence

The Checkout Field Manager for WooCommerce plugin contains an unauthenticated file upload vulnerability in the ajax_checkout_attachment_upload function. The function fails to verify user authentication or authorization before processing file upload requests, allowing any visitor to upload files to the server. While uploads are restricted to WordPress default allowed MIME types (images, documents), this still enables unauthorized file storage on the affected site.

MitigationUpdate the plugin to version 7.8.2 or later which contains proper authorization checks. As an interim measure, disable the plugin or restrict access to the upload functionality via web server rules until a patch can be applied.

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. Verify the plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and locate 'Checkout Field Manager for WooCommerce' or check the plugin files in /wp-content/plugins/ for the checkout-field-manager directory.
    Affected if The plugin is not installed or not present in the system.
  2. Identify the installed plugin version
    In WordPress admin Plugins list, click on the plugin name to view details and find the version number. Alternatively, check the main plugin PHP file for the 'Version' header comment in the plugin directory.
    Affected if Unable to determine the version or version is below 7.8.2.
  3. Confirm the vulnerable endpoint is accessible
    Check if the WordPress AJAX endpoint /wp-admin/admin-ajax.php is accessible and responds to the action 'cfm_checkout_attachment_upload'. This can be tested by examining the plugin JavaScript files that enqueue the upload handler, or by reviewing the ajax_checkout_attachment_upload function in the plugin code.
    Affected if The ajax_checkout_attachment_upload function exists and is registered without authentication checks.
  4. Verify file upload functionality is enabled
    Check the plugin settings in WooCommerce > Checkout Fields to see if any field types with file upload capability (such as file upload or image upload fields) are enabled on any checkout form.
    Affected if File upload fields are enabled and accessible to unauthenticated users on the checkout page.

A user is affected if the Checkout Field Manager for WooCommerce plugin is installed with a version earlier than 7.8.2 and the file upload feature is enabled on their checkout forms.
