CVE-2026-88814 · Severity: info · Published 2026-11-05

The YITH WooCommerce Gift Cards plugin for WordPress contains a race condition in gift card redemption that allows an attacker with a valid gift card code to spend more than the card's funded value. By submitting multiple checkout requests simultaneously, an attacker can bypass balance checks and overdraw the gift card, potentially obtaining merchandise or services without proper payment.

## 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.
