CVE-2025-8413The Listeo theme for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `soundcloud` shortcode in version less than, or equal to, 2.0.8 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.
