Vulnerability Overview

The Product Addons & Fields for WooCommerce plugin for WordPress is vulnerable to Content Injection in all versions up to, and including, 32.0.20. This is due to the plugin not properly validating a field that can be updated. This makes it possible for unauthenticated attackers to inject arbitrary content.

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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Remediation

Update to version 32.0.21, 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: PPOM 32.0.21 closes this, and updating the plugin is the step that ends it.
