Authenticated database disclosure via stored quiz answers
Published Jul 16, 2026 · Updated Jul 16, 2026
SQL injection in Themeum Tutor LMS 4.0.0 and earlier allows remote authenticated users to extract database data through stored quiz answers. The quiz-abandon AJAX handler stores an attacker-controlled answer array, and the quiz-attempt-details REST path later incorporates the stored values into an insufficiently prepared SQL query. A custom-level account can plant the payload, but execution requires a privileged user or Tutor REST API key holder to request the affected attempt details.
