SQL Injection in SMS Alert WooCommerce Plugin

Publication date: 2026-07-28

Last updated on: 2026-07-28

Assigner: Wordfence

Description
The SMS Alert – SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to generic SQL Injection via 'checkout_payment_plans' and 'order_status' Settings in all versions up to, and including, 3.9.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: the malicious payload is stored in the 'checkout_payment_plans' and 'order_status' settings via update_option() and executed later when the cod_to_prepaid_cart_notification_sendsms_hook WP-Cron event fires SA_CodTOPrepaid::sendSms().

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a second-order SQL injection vulnerability in the SMS Alert plugin for WordPress. It allows authenticated attackers with admin access to inject malicious SQL queries via the checkout_payment_plans and order_status settings. The payload is stored and later executed when a specific WP-Cron event runs.

Detection Guidance

This vulnerability requires checking WordPress plugin settings and database entries. Inspect the 'checkout_payment_plans' and 'order_status' options in the WordPress database for suspicious SQL payloads. Use SQL queries like SELECT option_name, option_value FROM wp_options WHERE option_name IN ('checkout_payment_plans', 'order_status'); to review stored values.

Impact Analysis

An attacker could extract sensitive data from the database, such as user credentials or personal information. Since it requires admin access, the risk is limited to compromised admin accounts or insider threats.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection. Organizations may face fines or penalties if such breaches occur due to inadequate security measures.

Mitigation Strategies

Immediately update the SMS Alert plugin to the latest version if available. If not, disable the plugin until a patch is released. Review and remove any unauthorized SQL code in the 'checkout_payment_plans' and 'order_status' settings. Ensure all administrator accounts are secure and monitor for unusual database activity.
