Impact
The vulnerability resides in improper input validation of the qty parameter within the woodmart_update_cart_item function in the WoodMart WooCommerce theme. By sending fractional values, attackers can reduce the effective quantity to negligible amounts that cause the cart total to round to $0.00, thereby allowing unauthenticated users to obtain virtual or downloadable products without payment. This flaw permits direct manipulation of the shopping cart without authentication, potentially leading to significant financial loss for site owners.
Affected Systems
The problem affects the WoodMart theme sold by xTemos for WordPress environments, specifically all releases up to and including version 8.2.6. Any WordPress site that has not applied a later update is susceptible to this issue.
Risk and Exploitability
The CVSS score of 5.3 places this flaw in the medium severity range, and the EPSS score of less than 1% indicates a low likelihood of exploitation under current conditions. The vulnerability is not listed in the CISA KEV catalog. Based on the description, the attack vector is unauthenticated and relies on a public web interface, making it plausible for anyone to craft the needed request to manipulate the cart.
