This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page."}, {"lang": "es", "value": "El plugin Ad Short para WordPress es vulnerable a Cross-Site Scripting Almacenado a trav\u00e9s del atributo 'client' del shortcode 'ad' en todas las versiones hasta la 2.0.1 inclusive.
