Descriptions

The Elementor Website Builder WordPress plugin before 3.4.8 does not sanitise or escape user input appended to the DOM via a malicious hash, resulting in a DOM Cross-Site Scripting issue.

El plugin Elementor Website Builder de WordPress versiones anteriores a 3.4.8, no sanea ni escapa de la entrada del usuario añadida al DOM por medio de un hash malicioso, resultando en un problema de tipo Cross-Site Scripting DOM

The Elementor Website Builder plugin for WordPress is vulnerable to DOM-based Cross-Site Scripting via the '#elementor-action:action=lightbox&settings=' DOM in versions up to, and including, 3.4.7 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.
