Technical details
The plugin fails to lock or atomically update a gift card's balance during the redemption process at checkout, creating a race condition (CWE-362). An unauthenticated attacker holding a gift card code can exploit this by issuing concurrent checkout requests with the same code; due to unsynchronized balance updates, multiple transactions can each succeed before the balance is decremented, allowing the attacker to exceed the funded value.
