CVE-2026-88814YITH WooCommerce Gift Cards race condition
CVE-2026-88814 is a race condition in YITH WooCommerce Gift Cards, rated low (3.7 on CVSS 3.1).
Why this priority: Low severity, with no exploitation signal.
Published · Updated · NVD status: Deferred
What it is
Two operations race on shared state, and an attacker who wins the race bypasses a check or corrupts data.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker win a timing window to bypass a check or corrupt shared state.
Is it being exploited?
There is no public report of exploitation yet. EPSS estimates a 0.13% chance of exploitation activity in the next 30 days, higher than 3% of scored CVEs.
What to do
- Upgrade YITH WooCommerce Gift Cards to 4.38.1 or later.
- Until it is patched, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
The YITH WooCommerce Gift Cards WordPress plugin before 4.38.1 does not lock or atomically update a gift card's balance when it is redeemed at checkout, allowing an attacker who holds a gift card code to spend more than its funded value by submitting multiple checkouts for the same code at the same time.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- WordPress sites and their plugins. Plugins run inside the site with its database access, and many sites are public.
- Request handlers and jobs that share state. The flaw sits between concurrent requests or processes.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- Between concurrent requests or processes. An attacker who crosses it can win a timing window to bypass a check or corrupt shared state.
Questions to answer about your own systems
- Where does YITH WooCommerce Gift Cards run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
