 "title": "LifterLMS <= 10.3.2 - Authenticated (Subscriber+) HTML Injection via Quiz Attempt Answers",
 "description": "The LifterLMS plugin for WordPress is vulnerable to HTML Injection via quiz attempt answers in all versions up to, and including, 10.3.2 due to insufficient sanitization of student-submitted answer HTML, which allowed form controls and data-* attributes, before it is displayed to instructors inside the quiz grading form. This makes it possible for authenticated attackers with student (subscriber-level) access to inject form fields and data attributes that the grading scripts read, which can manipulate the grading form when an instructor reviews the attempt.",
