DescriptionCVE.org

The LifterLMS plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter in all versions up to, and including, 9.2.1. This is 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 and above who have the edit_post capability on the quiz, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

AnalysisAI

SQL injection in LifterLMS WordPress plugin versions up to 9.2.1 allows authenticated Instructor-level users with edit_post capability to extract sensitive database information via insufficiently escaped 'order' parameter in quiz reporting tables. The vulnerability requires authenticated access with specific WordPress role and post capabilities, limiting exposure to trusted users with elevated privileges; no public exploit code or active exploitation has been identified at time of analysis.

Technical ContextAI

LifterLMS is a WordPress Learning Management System plugin that manages course content, quizzes, and student progress through custom post types and database tables. The vulnerability exists in quiz reporting functionality, specifically in the 'llms.table.quiz.non.attempts.php' file where the 'order' parameter is passed directly into SQL ORDER BY clauses without proper escaping via wpdb->prepare(). The root cause (CWE-89: SQL Injection) stems from concatenating user-supplied input into dynamic SQL queries rather than using parameterized prepared statements. The affected CPE indicates all versions of the LifterLMS plugin distributed through WordPress.org plugin repository are potentially vulnerable up to version 9.2.1.

RemediationAI

Upgrade LifterLMS to version 9.2.2 or later, which resolves the SQL injection by implementing proper query parameterization using WordPress wpdb->prepare() method. Update can be applied directly from the WordPress plugin dashboard (Plugins > Installed Plugins > LifterLMS > Update). For sites unable to update immediately, restrict edit_post capability on quiz post types to only trusted administrators and monitor database logs for suspicious SQL patterns. WordPress administrators should audit user roles and capabilities to ensure only necessary users retain Instructor-level or higher permissions.
