At a glance
CVE-2023-32963 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Predictive Search for WooCommerce WordPress plugin, affecting versions <= 5.8.0. 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 5.8.1; sites on affected versions should update now. Disclosed May 2023, reported by Kévin Mosbahi (Mika).
Vulnerability Overview
The WooCommerce Predictive Search plugin for WordPress is vulnerable to unauthorized modification of data due to a missing nonce check on multiple ajax sync functions in versions up to, and including, 5.8.0. This makes it possible for unauthenticated attackers to sync various product search results such as categories and SKUs, granted they can trick another user 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, and no interaction from a victim user.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Predictive Search for WooCommerce <= 5.8.0 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 Predictive Search for WooCommerce the fix is 5.8.1: builds <= 5.8.0 are affected, anything from 5.8.1 onward is not.
Remediation
Update to version 5.8.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Predictive Search for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Predictive Search for WooCommerce 5.8.1 closes this, and updating the plugin is the step that ends it.
