Descriptions

An issue was discovered in the Currency Switcher addon before 2.11.2 for WooCommerce if a user provides a currency that was not added by the administrator. In this case, even though the currency does not exist, it will be selected, but a price amount will fall back to the default currency. This means that if an attacker provides a currency that does not exist and is worth less than this default, the attacker can eventually purchase an item for a significantly cheaper price.

Se detectó un problema en el addon Currency Switcher anteriores a 2.11.2 para WooCommerce, si un usuario suministra una moneda que no fue agregada por el administrador. En este caso, aunque la moneda no exista, será seleccionada, pero el monto del precio regresará a la moneda predeterminada. Esto significa que si un atacante suministra una moneda que no existe y vale menos que este valor predeterminado, el atacante puede comprar un artículo a un precio significativamente más barato.
