CVE-2025-30807: Next-Cart to WooCommerce Migration SQLi

CVE-2025-30807 Overview

CVE-2025-30807 is a SQL Injection vulnerability affecting the Next-Cart Store to WooCommerce Migration plugin for WordPress, developed by Martin Nguyen. This vulnerability exists due to improper neutralization of special elements used in SQL commands, allowing attackers to execute arbitrary SQL queries against the underlying database. The vulnerability can be exploited remotely without authentication, potentially leading to unauthorized access to sensitive data stored in the WordPress database.

Critical Impact
Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive database contents, including user credentials, customer information, and potentially gain unauthorized access to the WordPress installation.

Affected Products

Next-Cart Store to WooCommerce Migration plugin versions up to and including 3.9.4
WordPress installations running the vulnerable plugin versions
WooCommerce stores using the Next-Cart migration functionality

Technical Details for CVE-2025-30807

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) in the Next-Cart Store to WooCommerce Migration plugin allows attackers to manipulate SQL queries through improperly sanitized user input. The plugin fails to adequately validate and sanitize user-supplied data before incorporating it into SQL statements, creating a direct injection point that can be exploited over the network.

The vulnerability is particularly concerning because it requires no authentication and no user interaction to exploit. Attackers can leverage this flaw to extract confidential information from the database, including but not limited to WordPress user accounts, WooCommerce customer data, order information, and payment details that may be stored in the database.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize and parameterize user-supplied input before constructing SQL queries. The plugin likely concatenates user input directly into SQL statements without using prepared statements or proper input validation, allowing malicious SQL syntax to be interpreted as part of the query structure rather than as data.

Attack Vector

The attack vector is network-based, meaning an attacker can exploit this vulnerability remotely over the internet. The attack does not require authentication or any special privileges on the target WordPress installation. The changed scope indicator in the CVSS vector suggests that the vulnerability can affect resources beyond the vulnerable component itself, potentially impacting the confidentiality of the entire database.

An attacker would typically craft malicious HTTP requests containing SQL injection payloads targeting vulnerable parameters in the plugin's functionality. Common techniques include UNION-based injection to extract data, boolean-based blind injection, or time-based blind injection depending on the specific vulnerable endpoint.

Detection Methods for CVE-2025-30807

Indicators of Compromise

Unusual database queries in WordPress/MySQL logs containing SQL injection patterns such as UNION SELECT, OR 1=1, or encoded variants
Unexpected HTTP requests to plugin endpoints with suspicious parameter values
Database access logs showing queries against sensitive tables (wp_users, wp_usermeta, WooCommerce order tables) from unexpected sources
Error messages in web server logs indicating SQL syntax errors that may suggest injection attempts

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting WordPress plugins
Monitor WordPress database query logs for anomalous query structures or unexpected data extraction patterns
Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
Review access logs for requests to the Next-Cart plugin endpoints with unusually long or encoded parameter values

Monitoring Recommendations

Enable detailed logging for WordPress database connections and monitor for queries with injection indicators
Set up alerts for failed SQL queries that may indicate injection probing attempts
Monitor outbound network traffic from the database server for potential data exfiltration
Implement real-time security monitoring for the WordPress installation using endpoint detection and response (EDR) solutions

How to Mitigate CVE-2025-30807

Immediate Actions Required

Update the Next-Cart Store to WooCommerce Migration plugin to a patched version as soon as one becomes available
If no patch is available, consider temporarily deactivating the plugin until a fix is released
Review WordPress and database access logs for any signs of exploitation attempts
Implement WAF rules to block SQL injection attempts targeting the vulnerable plugin
Restrict access to the WordPress admin area and limit plugin functionality to trusted users only

Patch Information

Organizations should monitor the Patchstack Vulnerability Report for updates on patch availability. The affected versions include all releases from n/a through 3.9.4. Plugin updates should be applied through the WordPress dashboard as soon as a security patch is released by the vendor.

Workarounds

Temporarily deactivate the Next-Cart Store to WooCommerce Migration plugin if it is not actively being used for migration tasks
Deploy a Web Application Firewall (WAF) with SQL injection protection rules enabled
Implement database-level access controls to limit the permissions of the WordPress database user
Use security plugins that provide virtual patching capabilities to protect against known vulnerabilities while awaiting an official fix

bash

# WordPress CLI commands for mitigation
# Deactivate the vulnerable plugin temporarily
wp plugin deactivate nextcart-woocommerce-migration

# Check current plugin version
wp plugin get nextcart-woocommerce-migration --field=version

# Update plugin when patch is available
wp plugin update nextcart-woocommerce-migration

# Review recently modified database tables for signs of tampering
wp db query "SHOW TABLE STATUS WHERE Update_time > NOW() - INTERVAL 7 DAY"
