- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- Unknown Wallet System for WooCommerce: from 2.0.0, fixed in 2.8.0

## Description

The Wallet System for WooCommerce WordPress plugin before 2.8.0 does not validate that a wallet transfer amount is positive, and computes the sender's new balance from a stale snapshot taken before crediting the recipient, allowing an authenticated attacker with Subscriber-level access to mint wallet funds for themselves or drain a specific victim's balance into their own account.
