What is CVE-2026-8653?

The MasterStudy LMS Pro Plus plugin for WordPress is susceptible to SQL Injection attacks through the 'columns' parameter. This vulnerability arises from inadequate escaping of user-supplied input, combined with insufficient parameter preparation in SQL queries. As a result, authenticated users with instructor-level access or higher can manipulate existing SQL queries, potentially leading to unauthorized access to sensitive information within the database. Website administrators are urged to apply available patches to safeguard against these security risks.
