## What it looks like

An extension trusts a client-submitted total instead of recalculating server-side.

## Why it matters

A buyer may be charged less than the actual order value.

## What to check

Review custom cart logic and reconcile final totals on the server.

## Documentation

This is an exploit pattern to check in installed components, not a claim that every WordPress site has this flaw. Confirm the product and version against its advisories before treating a site as affected. See [WooCommerce REST API overview](https://developer.woocommerce.com/docs/apis/), [WooCommerce security FAQ](https://woocommerce.com/document/woocommerce-security-faq/).
