qnotsquiz <= 1.0.0 - Authenticated (Admin+) Stored Cross-Site Scripting

Published Oct 24, 2025 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The qnotsquiz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'qnotsquiz_custom_start_text' parameter in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
