CVE-2025-14843 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the Wizit Gateway for WooCommerce plugin for WordPress. The vulnerability exists in the 'handle_checkout_redirecturl_response' function, which processes order cancellation requests. Due to the absence of proper authentication and authorization checks, an unauthenticated attacker can craft and send HTTP requests containing valid WooCommerce order IDs to cancel arbitrary orders. This bypasses any intended access controls and allows manipulation of order states without requiring user credentials or interaction. The vulnerability affects all versions up to and including 1.2.9 of the plugin. The CVSS v3.1 base score is 5.3 (medium severity), reflecting the network attack vector, no privileges required, no user interaction, and limited impact confined to integrity (order cancellation) without affecting confidentiality or availability. Although no public exploits are known, the vulnerability could be leveraged to disrupt e-commerce operations by malicious actors, potentially causing financial loss and undermining customer trust. The plugin is used in WooCommerce environments, which are widely deployed across small and medium-sized online retailers, making the attack surface significant. The lack of patches at the time of reporting necessitates immediate mitigation efforts by affected organizations.

The primary impact of this vulnerability is the unauthorized cancellation of legitimate WooCommerce orders, which compromises the integrity of e-commerce transactions. For European organizations, this can lead to direct financial losses due to disrupted sales and order fulfillment processes. Additionally, repeated or large-scale exploitation could damage customer trust and brand reputation, especially for businesses relying heavily on online sales. The vulnerability does not expose sensitive customer data or affect system availability, but the manipulation of order states can cause operational chaos, requiring manual reconciliation and customer service interventions. In sectors such as retail, logistics, and services where WooCommerce is prevalent, this could translate into significant operational overhead and potential regulatory scrutiny if customer service levels degrade. The impact is amplified in countries with high e-commerce penetration and strict consumer protection laws, where order integrity is critical. Furthermore, attackers could use this vulnerability as part of broader fraud schemes or to disrupt competitors’ business operations.

1. Monitor the Wizit Gateway for WooCommerce plugin vendor announcements closely and apply security patches immediately once released. 2. Until patches are available, implement Web Application Firewall (WAF) rules to detect and block unauthorized requests targeting the 'handle_checkout_redirecturl_response' endpoint, especially those attempting order cancellations without valid authentication tokens. 3. Restrict access to the order cancellation functionality by enforcing authentication and authorization at the application or server level, such as IP whitelisting or requiring valid session cookies. 4. Enable detailed logging and real-time monitoring of order cancellation events to detect anomalies or spikes indicative of exploitation attempts. 5. Educate e-commerce administrators to review order cancellation workflows and verify any unusual cancellations with customers directly. 6. Consider deploying additional security plugins or custom code to add authorization checks if immediate patching is not feasible. 7. Regularly audit WooCommerce and plugin configurations to ensure no unnecessary exposure of sensitive endpoints. 8. Conduct penetration testing focused on order management functions to identify similar authorization weaknesses.
