Description
The Ultimate Gift Cards for WooCommerce plugin for WordPress is vulnerable to a race condition in the gift card redemption features (redeeming a card for reward points and recharging a wallet with a card) in all versions up to, and including, 3.2.12. This is because the redemption handlers read the card balance, credit it to the user and set it to zero as separate, non-atomic steps. This makes it possible for authenticated attackers, with subscriber-level access and above, who hold a gift card to send concurrent redemption requests and have the same balance credited several times as points or wallet funds.
