Executive Summary

The Quiz Maker by AYS plugin for WordPress has a vulnerability known as Stored Cross-Site Scripting (XSS) in the 'rate_reason' parameter. This occurs because the plugin does not properly sanitize or escape input and output data. As a result, an attacker who is not authenticated can inject malicious web scripts into pages. These scripts will then execute whenever any user accesses the affected page.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary scripts in the context of users visiting the affected pages.
