SQL Injection in MasterStudy LMS Pro Plus WordPress Plugin

Publication date: 2026-06-04

Last updated on: 2026-06-04

Assigner: Wordfence

Description
The MasterStudy LMS Pro Plus plugin for WordPress is vulnerable to generic SQL Injection via the 'columns' parameter in all versions up to, and including, 4.8.20 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 instructor-level access or above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

AI Powered Q&A
Can you explain this vulnerability to me?

The MasterStudy LMS Pro Plus plugin for WordPress has a vulnerability known as generic SQL Injection in its 'columns' parameter. This issue exists in all versions up to and including 4.8.20. The vulnerability arises because the plugin does not properly escape user-supplied input and does not sufficiently prepare the SQL queries. As a result, authenticated users with instructor-level access or higher can inject additional SQL commands into existing queries.

This injection allows these users to manipulate the database queries, potentially extracting sensitive information from the database.


How can this vulnerability impact me? :

This vulnerability can impact you by allowing authenticated users with instructor-level access or above to extract sensitive information from the database. Since the SQL Injection flaw lets attackers append additional SQL queries, they can access data that should be protected.

The impact is rated with a CVSS v3.1 base score of 6.5, indicating a medium severity with high confidentiality impact but no impact on integrity or availability.
