      "value": "The Simple Download Counter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sdc_menu' shortcode in all versions up to, and including, 2.3. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes, specifically the 'text' and 'cat' attributes. The 'text' attribute is output directly into HTML content on line 159 without any escaping (e.g., esc_html()). The 'cat' attribute is used unescaped in HTML class attributes on lines 135 and 157 without esc_attr(). 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."

Esto se debe a una sanitización de entrada y un escape de salida insuficientes en los atributos de shortcode proporcionados por el usuario, específicamente los atributos 'text' y 'cat'. El atributo 'text' se envía directamente al contenido HTML en la línea 159 sin ningún escape (p. ej., esc_html()). El atributo 'cat' se utiliza sin escape en los atributos de clase HTML en las líneas 135 y 157 sin esc_attr(). 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."
