SMS Alert subscriber campaign permits administrator-level SQL injection
SMS Alert through 3.9.7 exposes an SQL-injection path on its manage_options All Subscriber page. All_Subscriber_List::processBulkAction() reads selected ID request values for the sa_sub_sendsms bulk action and passes them as post_ids to template/sms_campaign.php; the template interpolates each value directly into a subscriber SELECT query. An Administrator can inject SQL and extract database data. SMS Alert 3.9.8 casts the identifier with absint() and parameterizes the queries. The CNA calls the parameter id; upstream code uses the selected ID request field.

Technical description
The SMS Alert – SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to generic SQL Injection via the 'id' 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.
