What is CVE-2025-12075?

CVE-2025-12075 is a medium severity vulnerability in the Order Splitter for WooCommerce plugin for WordPress. It allows authenticated users with Subscriber-level access or higher to access sensitive order information of other users due to a missing authorization check on the ‘wos_troubleshooting’ AJAX endpoint.

How does this vulnerability work?

The vulnerability exists because the ‘wos_troubleshooting’ function does not verify user capabilities or nonce tokens before processing requests. An authenticated user can send a POST request to the AJAX endpoint with another user’s order ID, resulting in unauthorized access to that order’s details.

Who is affected by this vulnerability?

Any WordPress site using the Order Splitter for WooCommerce plugin version 5.3.5 or earlier is affected. This includes users with Subscriber roles or higher who can exploit the vulnerability to view other users’ order information.

How can I check if my site is vulnerable?

To check if your site is vulnerable, verify the version of the Order Splitter plugin installed. If it is version 5.3.5 or earlier, your site is vulnerable. Additionally, review your site’s logs for unauthorized access attempts to the ‘wos_troubleshooting’ endpoint.

How can I fix this vulnerability?

To fix the vulnerability, update the Order Splitter for WooCommerce plugin to version 5.3.6 or later, where the issue has been patched. Ensure that you also implement best practices for user permissions and regularly review plugin updates.

What does a CVSS score of 4.3 mean?

A CVSS score of 4.3 indicates a medium severity vulnerability. This means that while the vulnerability is not critical, it poses a significant risk, especially in environments where authenticated users have access to sensitive data.

What are the potential risks of this vulnerability?

If exploited, this vulnerability can lead to unauthorized disclosure of sensitive order information, including product details and customer data. This can result in privacy violations and potential exploitation of business intelligence.

How does the proof of concept demonstrate the issue?

The proof of concept provided shows how an authenticated user can exploit the vulnerability by sending a crafted POST request to the AJAX endpoint with another user’s order ID. It illustrates the steps to authenticate and retrieve sensitive order information without proper authorization.

What security controls were added in the patch?

The patch for CVE-2025-12075 implements nonce verification, adds capability checks for user permissions, and sanitizes input data. These controls ensure that only authorized users can access the troubleshooting endpoint and prevent unauthorized data exposure.

What should I do if I cannot update the plugin immediately?

If immediate updating is not possible, consider disabling the Order Splitter for WooCommerce plugin until you can apply the patch. Additionally, review user roles and restrict access to the AJAX endpoint to minimize the risk of exploitation.

How can I stay informed about vulnerabilities?

To stay informed about vulnerabilities, subscribe to security mailing lists, monitor the WordPress Plugin Repository for updates, and follow security-focused blogs and forums. Regularly check for updates to all installed plugins and themes.

What is nonce verification and why is it important?

Nonce verification is a security feature in WordPress that helps protect against Cross-Site Request Forgery (CSRF) attacks. It ensures that requests made to the server are intentional and come from authenticated users, thereby preventing unauthorized actions.

Analysis Overview

Atomic Edge analysis of CVE-2025-12075:
The Order Splitter for WooCommerce plugin for WordPress contains a missing authorization vulnerability in its troubleshooting AJAX endpoint. This flaw allows authenticated users with Subscriber-level permissions or higher to access sensitive order information belonging to other users. The vulnerability affects all plugin versions up to and including 5.3.5, with a CVSS score of 4.3.

The root cause is the absence of capability checks and nonce verification in the `wos_troubleshooting()` function within `/woo-order-splitter/inc/functions-troubleshooting.php`. The vulnerable code begins execution at line 3 by directly extracting `$_POST` data without validation. It immediately processes the `order_id` parameter to fetch and display order details. No authorization checks exist before the function accesses sensitive order metadata, item data, shipping information, and vendor details through WooCommerce API calls like `wc_get_order()`, `$order->get_items()`, and `get_post_field()`.

Exploitation requires an authenticated WordPress user with any role (including Subscriber) to send a POST request to `/wp-admin/admin-ajax.php` with the `action` parameter set to `wos_troubleshooting`. The attacker must include a valid `order_id` parameter pointing to another user’s order. The AJAX endpoint then returns detailed debugging information containing product names, vendor IDs, item metadata, shipping details, and order configuration settings without verifying the requester’s permission to view that order.

The patch adds three security controls. First, it implements nonce verification by checking `$_POST[‘wc_os_nonce’]` against `wp_verify_nonce()` with action `’wc_os_nonce_action’`. Second, it adds a capability check requiring either `manage_woocommerce` or `edit_shop_orders` permissions, which are typically reserved for shop managers and administrators. Third, it sanitizes the `order_id` input using `intval()`. These changes restrict endpoint access to authorized personnel only and prevent CSRF attacks.

Successful exploitation exposes sensitive order information including product details, vendor relationships, item metadata, shipping data, and order configuration. Attackers can harvest commercial intelligence, map vendor networks, and potentially gather data for social engineering or competitive analysis. While the vulnerability does not allow order modification, the information disclosure violates customer privacy and business confidentiality.
