Advisory
Source description from Wordfence Intelligence, credited to Ryan Fabella.
The YITH WooCommerce Gift Cards plugin for WordPress is vulnerable to Race Condition in all versions up to, and including, 4.38.0. This is due to a non-atomic read-modify-write operation on gift card balance that allowed concurrent checkouts to bypass the balance check before it was decremented. This makes it possible for unauthenticated attackers to spend more than the funded value of a gift card by submitting simultaneous checkout requests, exploiting the non-atomic read-modify-write balance update. The attacker must possess a valid gift card code with a non-zero balance.
