CVE-2025-48331: WooCommerce Exporter Data Disclosure Flaw

CVE-2025-48331 Overview

CVE-2025-48331 is a Sensitive Data Exposure vulnerability affecting the WooCommerce Orders & Customers Exporter plugin developed by vanquish. This WordPress plugin vulnerability allows unauthenticated attackers to retrieve embedded sensitive data from WooCommerce stores, potentially exposing customer orders and personal information to unauthorized parties.

The vulnerability stems from an Insertion of Sensitive Information Into Sent Data issue (CWE-201), where the plugin improperly handles sensitive customer and order data during export operations. This allows attackers to access confidential e-commerce data without proper authorization.

Critical Impact

Unauthenticated attackers can remotely extract sensitive WooCommerce customer and order data, potentially exposing personal information, order history, and other confidential e-commerce records.

Affected Products

• WooCommerce Orders & Customers Exporter plugin versions through 5.0
• WordPress installations running the vulnerable plugin
• WooCommerce stores utilizing the affected export functionality

Technical Details for CVE-2025-48331

Vulnerability Analysis

This vulnerability falls under CWE-201 (Insertion of Sensitive Information Into Sent Data), a category of information disclosure flaws where applications inadvertently include sensitive data in responses or exports that should be restricted.

The WooCommerce Orders & Customers Exporter plugin is designed to allow store administrators to export order and customer data for business operations. However, the vulnerability enables unauthorized retrieval of this sensitive information, bypassing the intended access controls.

The network-accessible nature of this flaw means attackers can exploit it remotely without requiring authentication or user interaction. The exploitation results in exposure of confidential data while maintaining system integrity and availability.

Root Cause

The root cause is improper access control in the plugin's data export functionality. The plugin fails to adequately verify user authorization before serving sensitive WooCommerce data, allowing the extraction of customer information and order details by unauthorized parties.

This represents a fundamental flaw in how the plugin handles authentication and authorization checks for its export operations, resulting in sensitive e-commerce data being accessible to unauthenticated users.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can remotely access the vulnerable export functionality to retrieve embedded sensitive data from the WooCommerce store.

Exploitation involves sending crafted requests to the WordPress site hosting the vulnerable plugin. The attacker can then extract customer personal information, order history, and other sensitive e-commerce data that should be restricted to authorized administrators.

Detection Methods for CVE-2025-48331

Indicators of Compromise

• Unusual access patterns to WooCommerce export endpoints or plugin files
• Unexpected HTTP requests targeting the woocommerce-orders-customers-exporter plugin directory
• Anomalous data transfer volumes from the WordPress installation
• Web server logs showing requests to export-related endpoints from unknown IP addresses
• Unauthorized access attempts to customer or order data export functionality

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block suspicious export requests
• Configure intrusion detection systems to alert on unusual data exfiltration patterns
• Review WordPress audit logs for unauthorized access to WooCommerce data

Monitoring Recommendations

• Enable detailed logging for WordPress and WooCommerce plugin activity
• Set up alerts for abnormal outbound data transfers from the web server

How to Mitigate CVE-2025-48331

Immediate Actions Required

• Deactivate and remove the WooCommerce Orders & Customers Exporter plugin immediately if running version 5.0 or earlier
• Audit web server logs for signs of exploitation or unauthorized data access
• Review customer and order data access patterns for anomalies
• Consider notifying affected customers if evidence of data exposure is discovered
• Update to a patched version of the plugin when available from the vendor

Patch Information

As of the last NVD update, organizations should check the Patchstack Vulnerability Report for the latest patch status and remediation guidance from the vendor. Users should upgrade to a version greater than 5.0 when a security fix becomes available.

Workarounds

• Disable the vulnerable plugin until a patch is available
• Implement IP-based access restrictions to the WordPress admin area
• Use a Web Application Firewall to block suspicious requests to plugin endpoints
• Restrict server-level access to the plugin directory using .htaccess or web server configuration

# Example .htaccess restriction for the vulnerable plugin directory
# Add to /wp-content/plugins/woocommerce-orders-customers-exporter/.htaccess
<IfModule mod_authz_core.c>
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</IfModule>
<IfModule !mod_authz_core.c>
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</IfModule>
