      "value": "The Reuse Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'reuse_builder_single_post_title' shortcode in all versions up to, and including, 1.7. This is due to insufficient input sanitization and output escaping on the 'style' attribute. 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."

      "value": "El plugin Reuse Builder para WordPress es vulnerable a cross-site scripting almacenado a través del shortcode 'reuse_builder_single_post_title' en todas las versiones hasta la 1.7, inclusive. Esto se debe a una sanitización de entrada insuficiente y a un escape de salida en el atributo 'style'. Esto hace posible que atacantes autenticados, con acceso de nivel de colaborador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
