CVE-2024-13456: Easy Quiz Maker <= 2.0 - Authenticated (Contributor+) Stored Cross-Site Scripting
Description
The Easy Quiz Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wqt-question' shortcode in all versions up to, and including, 2.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
