Description from the CNA
The Tutor LMS WordPress plugin before 4.2.0 does not prevent the correct answers to quiz questions from being included in the page it serves to the student taking the quiz, and does so regardless of the setting intended to control whether answers are revealed, allowing any enrolled student to obtain them before submitting their attempt.
