CVE-2026-32270 is a low-severity vulnerability impacting Craft Commerce, an ecommerce platform for Craft CMS. The vulnerability manifests in versions 4.0.0 through 4.10.2 and 5.0.0 through 5.5.4. An issue within the PaymentsController::actionPay allows unauthenticated users to access some order data when an order number is provided, and the email check fails during an anonymous payment. This JSON error response reveals serialized order objects containing sensitive information, including customer email, shipping address, and billing address.
The vulnerability is classified as low with a CVSS score of 1.7. While it does not have a significant impact on confidentiality, integrity, or availability, the potential exposure of sensitive customer information is a concern. As this vulnerability has been fixed in versions 4.11.0 and 5.6.0, organizations using affected versions should prioritize upgrading to mitigate the risk.
The urgency for remediation is moderate, as unauthorized access to customer data can lead to reputational damage and compliance issues. Organizations should ensure that their systems are updated to the latest versions to prevent potential data leaks.
Risk to organizations includes unauthorized access to sensitive order details, which can be exploited by malicious actors. Although there is no public exploit confirmed, the nature of the vulnerability warrants attention to avoid any future exploitation.
Given the low severity, organizations are encouraged to schedule remediation as part of their regular maintenance activities.
Vulnerability Details
The official description states: 'Craft Commerce is an ecommerce platform for Craft CMS. In versions 4.0.0 through 4.10.2 and 5.0.0 through 5.5.4, the PaymentsController::actionPay discloses some order data to unauthenticated users when an order number is provided and the email check fails during an anonymous payment. The JSON error response includes the serialized order object (order), which contains some sensitive fields such as customer email, shipping address, and billing address. This issue has been fixed in versions 4.11.0 and 5.6.0.'
The vulnerability type is classified under CWE-200 (Information Exposure) and CWE-862 (Inadequate Authentication). The CVSS score of 1.7 indicates a low severity level, meaning the risk associated with this vulnerability is relatively low.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user authorization during the payment process. The PaymentsController retrieves order data based on the order number without adequately enforcing authorization checks. This flaw allows unauthenticated users to gain access to sensitive information if they possess a valid order number.
The attack vector is network-based, and the attack complexity is low, as it does not require any special skills or extensive preparation to exploit. There are no privileges required, and user interaction is not necessary for successful exploitation.
In terms of impact, the vulnerability has a low confidentiality impact, meaning the exposure of sensitive data is limited. However, there is no integrity or availability impact associated with this vulnerability.
Risk & Impact Analysis
The real-world deployment risk of this vulnerability is predominantly associated with the potential exposure of customer information. While the overall risk is low due to the nature of the vulnerability, organizations must remain vigilant. The blast radius potential is limited to users who have access to valid order numbers, which may include internal staff or customers.
The urgency assessment based on CVSS indicates that organizations should address this vulnerability in their priority patch cycle to ensure that all systems are promptly updated.
