Descriptions

The Happy Addons for Elementor WordPress plugin before 2.24.0, Happy Addons Pro for Elementor WordPress plugin before 1.17.0 have a number of widgets that are vulnerable to stored Cross-Site Scripting(XSS) by lower-privileged users such as contributors, all via a similar method: The “Card” widget accepts a “title_tag” parameter. Although the element control lists a fixed set of possible html tags, it is possible to send a ‘save_builder’ request with the “heading_tag” set to “script”, and the actual “title” parameter set to JavaScript to be executed within the script tags added by the “heading_tag” parameter.

El plugin Happy Addons para Elementor WordPress versiones anteriores a 2.24.0, el plugin Happy Addons Pro para Elementor WordPress versiones anteriores a 1.17.0, presentan una serie de widgets que son vulnerables a un ataque de tipo Cross-Site Scripting (XSS) almacenado por usuarios pocos privilegiados, como contribuyentes, todos por medio de un método similar: el widget "Card" acepta un parámetro "title_tag". Aunque el control de elementos enumera un conjunto fijo de posibles etiquetas html, es posible enviar una petición "save_builder" con el "header_tag" ajustado en "script" y el parámetro "title" real ajustado en JavaScript para que sea ejecutado dentro del script. etiquetas agregadas por el parámetro "header_tag"
