## Description

The Wallet for WooCommerce plugin for WordPress is vulnerable to referral reward abuse in versions 1.7.2 up to, and including, 1.7.3, due to the self-referral detection comparing IP addresses taken from client-supplied forwarded headers such as X-Forwarded-For, with no daily cap on visit rewards per referrer. This makes it possible for authenticated attackers, with subscriber-level access and above, to use additional customer accounts and spoofed IP addresses to collect referral rewards in their own referrer wallet. Exploitation requires the referral program to be enabled.
