At a glance

CVE-2025-8097 is a medium-severity Improper Input Validation vulnerability in the Woodmart WordPress theme, affecting versions <= 8.2.6. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 8.2.7; sites on affected versions should update now. Disclosed July 2025, reported by Samir El Khaouti.

Vulnerability Overview

The WoodMart theme for WordPress is vulnerable to Improper Input Validation in all versions up to, and including, 8.2.6. This is due to insufficient validation of the qty parameter in the woodmart_update_cart_item function. This makes it possible for unauthenticated attackers to manipulate cart quantities using fractional values, allowing them to obtain products for free by setting extremely small quantities (e.g., 0.00001) that round cart totals to $0.00, effectively bypassing payment requirements and allowing unauthorized acquisition of virtual or downloadable products.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-20: Improper Input Validation

Reaching this weakness in Woodmart <= 8.2.6 takes no account at all. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Woodmart the fix is 8.2.7: builds <= 8.2.6 are affected, anything from 8.2.7 onward is not.

Remediation

Update to version 8.2.7, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Woodmart 8.2.7 closes this, and updating the theme is the step that ends it.
