SQL Injection in Tutor LMS WordPress Plugin

Publication date: 2026-07-28

Last updated on: 2026-07-28

Assigner: Wordfence

Description
The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via the 'coupon_code' parameter in all versions up to, and including, 4.0.1 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.

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.

Executive Summary

This vulnerability is a SQL Injection flaw in the Tutor LMS WordPress plugin. It allows authenticated attackers with administrator access or higher to inject malicious SQL code via the 'coupon_code' parameter. The issue arises due to insufficient input sanitization and lack of proper SQL query preparation, enabling attackers to manipulate database queries and potentially extract sensitive information.

Detection Guidance

This vulnerability can be detected by checking if the Tutor LMS plugin version is 4.0.1 or lower. Inspect WordPress plugin files for suspicious SQL queries or unauthorized database access patterns. Review server logs for unusual queries containing 'coupon_code' parameter manipulation.

Impact Analysis

If you use the Tutor LMS plugin on your WordPress site, an attacker with administrator privileges could exploit this flaw to access sensitive data stored in your database. This may include user credentials, personal information, or other confidential data, potentially leading to data breaches or further attacks on your site.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection. Organizations may face legal penalties, reputational damage, and loss of compliance certifications if such breaches occur due to inadequate security measures.

Mitigation Strategies

Immediately update the Tutor LMS plugin to the latest version. If updating is not possible, disable the plugin until a patch is applied. Restrict administrator-level access to only necessary users and monitor database queries for suspicious activity.
