Unauthenticated database disclosure via coupon lookup SQL injection
Published Feb 28, 2026 · Updated Feb 28, 2026
SQL injection in Themeum Tutor LMS 3.9.6 and earlier allows remote attackers to read database data through a crafted coupon_code value. The native eCommerce checkout passes coupon_code into a coupon lookup query without sufficient escaping or prepared-query parameterization, allowing appended SQL to alter the statement. No account is required, and successful exploitation discloses database contents; integrity and service availability impacts are not reported.
