## Description

The GPTranslate plugin for WordPress is vulnerable to Cross-Site Scripting via HTML attribute values in pages rendered by the server-side translation feature with the DOMDocument or SimpleHTMLDOM engine in all versions up to, and including, 2.34.13. This is due to insufficient output escaping: the translated page is entity-decoded after its attribute values have been escaped. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into translated pages that execute when a user accesses the affected page.
