# YITH WooCommerce Gift Cards: coupons let buyers get over-valued gift cards

Link for people: https://infrastack.ai/live/CVE-2026-88813 (this .md is for agents)

The YITH WooCommerce Gift Cards WordPress plugin, through version 4.39.0, issues gift cards worth the item's pre-discount price rather than the amount paid. A customer who applies a normal store coupon at checkout can receive a gift card worth more than they paid.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the YITH WooCommerce Gift Cards plugin is installed and its version is `4.39.0` or earlier.
- Review gift cards issued through checkout with coupons applied for values above the amount paid.

## From the sources

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.
