      "value": "The kk blog card plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'blog-card' shortcode in all versions up to, and including, 1.3. This is due to insufficient input sanitization and output escaping on the shortcode's 'href' and 'type' attributes, which are concatenated directly into HTML attribute contexts in the shortcode callback registered in kk-blog-card-shortcode.php. 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 kk blog card para WordPress es vulnerable a cross-site scripting almacenado a través del shortcode 'blog-card' del plugin en todas las versiones hasta la 1.3, inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en los atributos 'href' y 'type' del shortcode, los cuales se concatenan directamente en contextos de atributos HTML en la función de callback del shortcode registrada en kk-blog-card-shortcode.PHP. Esto permite a atacantes autenticados, con acceso de nivel de colaborador y superior, inyectar scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada."
