At a glance

CVE-2026-3589 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the WooCommerce WordPress plugin, affecting versions < 10.5.3. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 10.5.3; sites on affected versions should update now. Disclosed March 2026, reported by oolongeya.

Vulnerability Overview

The WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to 10.5.3 (exclusive). This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to perform an unauthorized action granted they can trick a site administrator into performing an action such as clicking on a link.

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.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in WooCommerce < 10.5.3 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For WooCommerce the fix is 10.5.3: builds < 10.5.3 are affected, anything from 10.5.3 onward is not.

Remediation

Update to version 10.5.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WooCommerce 10.5.3 closes this, and updating the plugin is the step that ends it.
