MDx <= 2.0.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via mdx_list_item Shortcode

Published Aug 12, 2024 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The MDx theme for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'mdx_list_item' shortcode in all versions up to, and including, 2.0.3 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.
