Summary
The YITH WooCommerce Gift Cards WordPress plugin through 4.39.0 does not reconcile the value of a gift card it issues against the amount actually paid for it, instead crediting the new card with the item's pre-discount price, which allows customers to apply an ordinary store coupon at checkout and receive a gift card worth more than they paid.
