MEDIUM CVE-2026-15670 Deferred

SMS Alert subscriber sorting permits administrator-level SQL injection

SMS Alert through 3.9.7 reads the orderby request parameter on its manage_options All Subscriber page in All_Subscriber_List::getAllSubscriber(). It applies only text sanitization and appends the value directly to the SQL ORDER BY clause before $wpdb->get_results(), enabling an Administrator to perform time-based SQL injection and extract database information. Version 3.9.8 restricts the sort column and direction to allow-lists and parameterizes pagination values.

Technical description

The SMS Alert – SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to time-based SQL Injection via the 'orderby' parameter 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.
