## Affected

- Unknown StoreGrowth: fixed in 2.1.2

## Description

The StoreGrowth WordPress plugin before 2.1.2 does not validate a browser-supplied product price on two of its unauthenticated actions, allowing unauthenticated attackers to add a product to the cart at an arbitrary, attacker-chosen price that carries through to the checkout total when the BOGO offer feature is enabled.

## What to do

- Check your stack: if you ship or depend on Unknown StoreGrowth, upgrade to a fixed version (2.1.2) per the references below.
