Descriptions

The WP Meta SEO WordPress plugin before 4.4.7 does not sanitise or escape the breadcrumb separator before outputting it to the page, allowing a high privilege user such as an administrator to inject arbitrary javascript into the page even when unfiltered html is disallowed.

El plugin WP Meta SEO de WordPress versiones anteriores a 4.4.7, no sanea ni escapa del separador breadcrumb antes de enviarlo a la página, lo que permite a un usuario con altos privilegios, como un administrador, inyectar javascript arbitrario en la página incluso cuando el html sin filtrar no está permitido
