CVE-2025-4099: List Children <= 2.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode
First published: Thu May 01 2025(Updated: )
The List Children plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'list_children' shortcode in all versions up to, and including, 2.1 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.
