CVE-2026-84925

The Avada | Website Builder For WordPress & WooCommerce theme for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'lang' parameter in all versions up to, and including, 7.16.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The injected value is propagated through Fusion Multilingual::set active language() and concatenated into a URL by Fusion Settings::get setting link() without applying urlencode(), esc url(), or esc attr() before being echoed raw into a double-quoted href attribute in the post editor metabox.
