CVE-2025-14843: Wizit Gateway Auth Bypass Vulnerability

CVE-2025-14843 Overview

The Wizit Gateway for WooCommerce plugin for WordPress contains an Unauthenticated Arbitrary Order Cancellation vulnerability in all versions up to, and including, 1.2.9. This security flaw stems from missing authentication and authorization checks in the handle_checkout_redirecturl_response function, allowing unauthenticated attackers to cancel arbitrary WooCommerce orders by sending crafted requests with valid order IDs.

Critical Impact

Unauthenticated attackers can disrupt e-commerce operations by canceling legitimate customer orders, potentially causing revenue loss, customer dissatisfaction, and operational chaos for affected online stores.

Affected Products

• Wizit Gateway for WooCommerce plugin versions up to and including 1.2.9
• WordPress installations running vulnerable plugin versions
• WooCommerce stores utilizing the Wizit Gateway payment integration

Technical Details for CVE-2025-14843

Vulnerability Analysis

This vulnerability is classified as CWE-862 (Missing Authorization), representing a fundamental access control flaw in the Wizit Gateway for WooCommerce plugin. The vulnerable code path exists within the handle_checkout_redirecturl_response function, which processes checkout redirect URL responses without verifying whether the requesting party has legitimate authorization to perform order status modifications.

The attack can be executed remotely over the network without requiring any form of authentication or user interaction. The vulnerability primarily impacts the integrity of WooCommerce order data, as attackers can manipulate order statuses without proper authorization. While confidentiality and availability are not directly compromised, the ability to cancel arbitrary orders represents a significant business logic flaw that can disrupt e-commerce operations.

Root Cause

The root cause of this vulnerability lies in the absence of authentication and authorization validation within the handle_checkout_redirecturl_response function. The plugin fails to verify that incoming requests originate from legitimate sources or that the requester has appropriate permissions to modify order statuses. This missing access control check allows any external party who can determine or enumerate valid order IDs to cancel orders they should not have access to.

Attack Vector

The attack vector for this vulnerability is network-based and requires no special privileges or user interaction. An attacker can exploit this flaw by:

1. Identifying valid WooCommerce order IDs through enumeration or information disclosure
2. Crafting malicious HTTP requests that target the vulnerable handle_checkout_redirecturl_response endpoint
3. Submitting the crafted requests with valid order IDs to trigger unauthorized order cancellations

The vulnerability manifests in the checkout redirect URL response handler where order status modifications are processed without proper authorization checks. Technical details and vulnerable code can be reviewed in the WordPress Plugin Code repository.

Detection Methods for CVE-2025-14843

Indicators of Compromise

• Unexpected order cancellations without corresponding customer requests or payment failures
• HTTP requests to checkout redirect URL endpoints from unusual or external IP addresses
• Patterns of sequential or bulk order cancellations occurring in rapid succession
• Server logs showing requests to the handle_checkout_redirecturl_response function with various order IDs

Detection Strategies

• Monitor WooCommerce order status changes and alert on cancellations not initiated through standard customer or admin workflows
• Implement web application firewall rules to detect and log suspicious patterns targeting the vulnerable endpoint
• Review server access logs for unusual request patterns to payment gateway callback URLs
• Configure intrusion detection systems to identify enumeration attempts against order endpoints

Monitoring Recommendations

• Enable detailed logging for all WooCommerce order status transitions
• Set up alerts for abnormal spikes in order cancellation rates
• Monitor for failed or suspicious requests to payment gateway integration endpoints
• Implement rate limiting on checkout-related API endpoints to slow enumeration attempts

How to Mitigate CVE-2025-14843

Immediate Actions Required

• Update the Wizit Gateway for WooCommerce plugin to a patched version (if available) immediately
• Audit recent order cancellations to identify any potentially unauthorized modifications
• Implement web application firewall rules to restrict access to the vulnerable endpoint
• Consider temporarily disabling the plugin until a security patch is applied

Patch Information

Organizations should check for plugin updates through the WordPress plugin repository or contact the plugin vendor for security patches. The vulnerability affects all versions up to and including 1.2.9. Review the Wordfence Vulnerability Report for the latest remediation guidance and patch availability information.

Workarounds

• Implement server-level access controls to restrict requests to payment gateway callback endpoints
• Add custom authorization checks at the web server or application level before requests reach the plugin
• Use a web application firewall to validate and filter incoming requests to the vulnerable function
• Monitor and respond to suspicious order cancellation patterns until a permanent fix is deployed
