      "value": "The TableOn – WordPress Posts Table Filterable plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tableon_button' shortcode in all versions up to and including 1.0.4.4. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'class', 'help_link', 'popup_title', and 'help_title'. The do_shortcode_button() function extracts these attributes without sanitization and passes them to TABLEON_HELPER::draw_html_item(), which concatenates attribute values into HTML using single quotes without escaping (line 29: $item .= \" {$key}='{$value}'\"). 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 TableOn - WordPress Posts Table Filterable para WordPress es vulnerable a cross-site scripting almacenado a través del shortcode 'tableon_button' en todas las versiones hasta la 1.0.4.4 inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en los atributos de shortcode proporcionados por el usuario, como 'class', 'help_link', 'popup_title' y 'help_title'. La función do_shortcode_button() extrae estos atributos sin sanitización y los pasa a TABLEON_HELPER::draw_html_item(), que concatena los valores de los atributos en HTML usando comillas simples sin escape (línea 29: $item .= \" {$key}='{$value}'\"). 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."
