CVE-2025-49352 identifies an authorization bypass vulnerability categorized under CWE-639 (Authorization Bypass Through User-Controlled Key) in the YoOhw Studio Order Cancellation & Returns plugin for WooCommerce. This vulnerability stems from incorrectly configured access control mechanisms that rely on user-controllable keys to authorize order cancellation or return requests. Specifically, the plugin fails to properly validate whether the requesting user has the necessary permissions to perform these sensitive actions, allowing attackers with limited privileges (PR:L) to bypass authorization checks without requiring user interaction (UI:N). The vulnerability affects all versions up to 1.1.10. Exploitation occurs remotely (AV:N) over the network, with low attack complexity (AC:L). The impact primarily affects integrity (I:L), as unauthorized users can manipulate order statuses, potentially causing financial discrepancies or customer service issues. Confidentiality and availability are not impacted. No public exploits or patches are currently available, but the vulnerability has been officially published and reserved in the CVE database. The flaw highlights a common security weakness in e-commerce plugins where access control is improperly implemented, emphasizing the need for robust authorization checks beyond user-supplied parameters.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the affected plugin, this vulnerability poses a risk of unauthorized order cancellations or returns. Such unauthorized actions can lead to financial losses, customer dissatisfaction, and reputational damage. Although the vulnerability does not compromise data confidentiality or system availability, the integrity of order data is at risk, which can disrupt business operations and complicate audit trails. Attackers with low-level privileges or compromised accounts could exploit this flaw to manipulate orders without detection. This risk is heightened in organizations with insufficient internal access controls or monitoring. Given the widespread use of WooCommerce in Europe, particularly among small to medium-sized enterprises, the vulnerability could have a broad impact if left unaddressed. Additionally, regulatory compliance related to transaction integrity and consumer protection may be affected if unauthorized order modifications occur.

1. Monitor YoOhw Studio’s official channels for security patches addressing CVE-2025-49352 and apply updates promptly once available. 2. Until patches are released, restrict access to the Order Cancellation & Returns plugin features to only highly trusted user roles with a demonstrated need. 3. Implement additional server-side authorization checks independent of user-controlled keys to validate permissions before processing cancellation or return requests. 4. Enable detailed logging and monitoring of order status changes to detect suspicious or unauthorized modifications quickly. 5. Conduct regular audits of user roles and permissions within WooCommerce to minimize the number of users with cancellation or return privileges. 6. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block anomalous requests targeting order cancellation endpoints. 7. Educate staff about the risks of privilege misuse and enforce strong authentication mechanisms to reduce the risk of account compromise. 8. Review and harden the overall WooCommerce environment, including plugins and themes, to reduce attack surface and prevent chained exploits.
