What is CVE-2026-15444?

The Tutor LMS plugin, a widely used solution for eLearning and online courses on WordPress, is exposed to SQL Injection vulnerabilities through the 'coupon_code' parameter. This issue arises from inadequate escaping of user-supplied input, allowing authenticated users with administrator-level access to inject malicious SQL commands into existing queries. Exploiting this vulnerability can lead to unauthorized access to sensitive database information, posing a significant risk to the integrity and confidentiality of user data in eLearning environments. Users are advised to update to the latest versions to mitigate this risk.
