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 WooCommerce PayPal Payments plugin for WordPress is vulnerable to unauthorized order manipulation and information disclosure due to missing authorization checks on the `ppc-create-order` and `ppc-get-order` WC-AJAX endpoints in all versions up to, and including, 4.0.1. The `ppc-create-order` endpoint accepts an arbitrary WooCommerce order ID in the `pay-now` context without validating order ownership, allowing attackers to create PayPal orders for any WC order and write PayPal metadata to it. The `ppc-get-order` endpoint returns full PayPal order details for any PayPal order ID without binding to the requester's session. This makes it possible for unauthenticated attackers to chain these endpoints to manipulate other customers' order payment flows and exfiltrate sensitive order details (payer information, shipping data) by creating a PayPal order for a victim's WC order and then retrieving the PayPal order data.

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 WooCommerce PayPal Payments plugin lacks authorization checks on two AJAX endpoints (ppc-create-order and ppc-get-order). Attackers can create PayPal orders for arbitrary WooCommerce orders without ownership validation, then retrieve full PayPal order details including payer information and shipping data by chaining these endpoints. This IDOR vulnerability allows unauthenticated users to manipulate any order and exfiltrate sensitive customer data.

MitigationUpdate to version 4.0.2 or later which includes proper authorization validation on the affected AJAX endpoints. Until patched, consider restricting access to these endpoints or implementing additional access controls at the web server level.

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 WooCommerce PayPal Payments plugin is installed
    Navigate to WordPress admin > Plugins and verify 'WooCommerce PayPal Payments' appears in the installed plugins list, or inspect the plugin directory at /wp-content/plugins/woocommerce-paypal-payments/
    Affected if The plugin is installed and active in WordPress
  2. Identify the installed plugin version
    In WordPress admin > Plugins, click on the plugin to view details and read the installed version number, or check the main plugin file (e.g., woocommerce-paypal-payments.php) for the 'Version:' header comment
    Affected if The installed version is lower than 4.0.2 (vulnerable versions: 1.x, 2.x, 3.x before 3.x.x) or cannot be determined
  3. Verify the vulnerable AJAX endpoints are accessible
    Send a GET request to yoursite.com/?wc-ajax=ppc-get-order with a test order ID parameter (e.g., ?order_id=1) using a tool like curl or Burp, without providing authentication cookies
    Affected if The endpoint responds with HTTP 200 and returns PayPal order data or JSON structure without requiring login credentials
  4. Test order manipulation capability
    Send a POST request to yoursite.com/?wc-ajax=ppc-create-order with a valid but unrelated WooCommerce order ID in the request body (e.g., order_id=999) without authentication
    Affected if The request succeeds and creates a PayPal order bound to the arbitrary order ID, returning order details without authorization validation

You are affected if the WooCommerce PayPal Payments plugin is installed with a version below 4.0.2 AND the ppc-create-order or ppc-get-order AJAX endpoints respond without requiring WordPress/WooCommerce session authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to version 4.0.2 or later which includes proper authorization validation on the affected AJAX endpoints. Until patched, consider restricting access to these endpoints or implementing additional access controls at the web server level.

Recommended fix Moderate confidence

4.0.2 or later (latest stable release)

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate the WooCommerce PayPal Payments plugin
  4. Check the current version (should be 4.0.1 or below if vulnerable)
  5. If an update is available, click 'Update Now' to install the latest version
  6. Alternatively, navigate to Dashboard > Updates and update the plugin from there
  7. After updating, verify the plugin version is newer than 4.0.1
