Vulnerability Overview

The wp-ultimate-csv-importer plugin before 5.6.1 for WordPress has CSRF.

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 WP Ultimate CSV Importer <= 5.6 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 WP Ultimate CSV Importer the fix is 5.6.1: builds <= 5.6 are affected, anything from 5.6.1 onward is not.

Remediation

Update to version 5.6.1, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Ultimate CSV Importer: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Ultimate CSV Importer 5.6.1 closes this, and updating the plugin is the step that ends it.
