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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

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

Reaching this weakness in Address Book for WooCommerce < 1.6.0 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 Address Book for WooCommerce the fix is 1.6.0: builds < 1.6.0 are affected, anything from 1.6.0 onward is not.

Remediation

Update to version 1.6.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Address Book for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Address Book for WooCommerce 1.6.0 closes this, and updating the plugin is the step that ends it.
