      "value": "The Paypal Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'amount' and 'name' shortcode attributes in all versions up to, and including, 0.3. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes. The swer_paypal_shortcode() function extracts shortcode attributes using extract() and shortcode_atts() at line 89, then directly concatenates the $name and $amount values into HTML input element value attributes at lines 105-106 without applying esc_attr() or any other escaping function. 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 Paypal Shortcode para WordPress es vulnerable a cross-site scripting almacenado a través de los atributos de shortcode 'amount' y 'name' en todas las versiones hasta la 0.3, inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes en los atributos de shortcode proporcionados por el usuario. La función swer_paypal_shortcode() extrae los atributos de shortcode usando extract() y shortcode_atts() en la línea 89, luego concatena directamente los valores $name y $amount en los atributos de valor de los elementos de entrada HTML en las líneas 105-106 sin aplicar esc_attr() ni ninguna otra función de escape. 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."
