      "value": "The Columns by BestWebSoft plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' shortcode attribute of the [print_clmns] shortcode in all versions up to and including 1.0.3. This is due to insufficient input sanitization and output escaping on the 'id' attribute. The shortcode receives the 'id' parameter via shortcode_atts() at line 596 and directly embeds it into HTML output at line 731 (in a div id attribute) and into inline CSS at lines 672-729 without any escaping or sanitization. While the SQL query uses %d to cast the value to an integer for database lookup, the original unsanitized string value of $id is still used in the HTML/CSS output. 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. The attack requires that at least one column exists in the plugin (created by an admin), as the SQL query must return results for the output branch to be reached."

      "value": "El plugin Columns by BestWebSoft para WordPress es vulnerable a Stored Cross-Site Scripting a través del atributo del shortcode 'id' del shortcode [print_clmns] en todas las versiones hasta la 1.0.3 inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en el atributo 'id'. El shortcode recibe el parámetro 'id' a través de shortcode_atts() en la línea 596 y lo incrusta directamente en la salida HTML en la línea 731 (en un atributo id de div) y en CSS en línea en las líneas 672-729 sin ningún escape o sanitización. Si bien la consulta SQL utiliza %d para convertir el valor a un entero para la búsqueda en la base de datos, el valor de cadena original no sanitizado de $id todavía se utiliza en la salida HTML/CSS. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. El ataque requiere que al menos una columna exista en el plugin (creada por un administrador), ya que la consulta SQL debe devolver resultados para que se alcance la rama de salida."
