Attack Vectors
Order Splitter for WooCommerce (slug: woo-order-splitter) is affected by a Medium-severity vulnerability (CVSS 4.3, CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) tracked as CVE-2025-12075.
The issue can be exploited by an attacker who already has a login with Subscriber-level access or higher. From there, they can target an AJAX endpoint used by the plugin (the wos_troubleshooting endpoint) to access information related to other customers’ orders—without needing to trick an admin or require additional user interaction.
This matters for organizations where many users have accounts (customers, partners, contractors, or internal staff) because a low-privilege account is often easier to obtain through password reuse, credential stuffing, or accidental account creation than an administrator account.
Security Weakness
The root cause is a missing authorization (capability) check on the plugin’s wos_troubleshooting AJAX endpoint in versions up to and including 5.3.5. In practical terms, the plugin does not sufficiently verify whether the logged-in user is allowed to view the requested order data.
Because the weakness affects an authenticated endpoint, it is not a “drive-by” public exploit—however, the required access level (Subscriber+) is low enough that it can still be a realistic threat for eCommerce brands and multi-user WordPress environments.
Remediation: Update Order Splitter for WooCommerce to version 5.3.6 or newer, which contains the fix.
Technical or Business Impacts
This vulnerability enables order information exposure. While the severity is rated Medium, the business impact can be significant because order records often contain customer-related details that can drive reputational damage and compliance exposure if accessed improperly.
Business risks you should consider: customer trust erosion, increased support burden (“why is my order visible?”), potential data protection obligations depending on what information is exposed, and downstream fraud or social engineering risks if attackers learn customer purchase patterns.
Operationally, this can also disrupt reporting integrity and executive visibility: if stakeholders suspect order data confidentiality is compromised, it can affect decision-making, partner confidence, and brand reputation—especially for organizations with regulated customers or strict contractual privacy commitments.
