Description

The Email Subscribers by Icegram Express – Email Marketing, Newsletters, Automation for WordPress & WooCommerce plugin for WordPress is vulnerable to SQL Injection via the 'run' function of the 'IG_ES_Subscribers_Query' class in all versions up to, and including, 5.7.14 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
