Description
The Quiz Maker plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 6.7.0.80. This is due to the plugin exposing quiz answers through the ays_quiz_check_answer AJAX action without proper authorization checks. The endpoint only validates a nonce, but that same nonce is publicly available to all site visitors via the quiz_maker_ajax_public localized script data. This makes it possible for unauthenticated attackers to extract sensitive data including quiz answers for any quiz question.

Executive Summary

The vulnerability in the Quiz Maker plugin for WordPress allows unauthenticated attackers to access sensitive information, specifically quiz answers. This happens because the plugin exposes quiz answers through an AJAX action called ays_quiz_check_answer without proper authorization checks. Although the endpoint validates a nonce, this nonce is publicly available to all site visitors, enabling attackers to extract quiz answers for any quiz question.

Impact Analysis

This vulnerability can lead to unauthorized disclosure of quiz answers, which may compromise the integrity of quizzes and assessments. Attackers can obtain correct answers without permission, potentially undermining the purpose of quizzes, affecting user trust, and damaging the reputation of the website or organization using the plugin.
