Vulnerability Overview

The Quiz And Survey Master – Best Quiz, Exam and Survey Plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 8.1.13 due to insufficient input sanitization and output escaping on user supplied attributes.
