Executive Summary

This is an Insecure Direct Object Reference (IDOR) vulnerability in the Quiz and Survey Master WordPress plugin before version 11.2.4. It allows users with Contributor-level access or higher to read the email-notification and results-page configurations of quizzes created by other users, including notification recipient addresses.
