What is CVE-2026-1258?

The Mail Mint plugin for WordPress is susceptible to blind SQL injection attacks due to improper handling of user-supplied input in several API endpoints, including 'forms', 'automation', 'email/templates', and 'contacts/import/tutorlms/map'. This vulnerability arises from insufficient escaping of parameters like 'order-by', 'order-type', and 'selectedCourses', combined with a lack of adequate preparation in the associated SQL queries. As a result, authenticated users with administrator privileges can exploit the flaw to append malicious SQL commands, potentially compromising the database integrity and security.
