At a glance

CVE-2024-43340 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Advanced Form Integration WordPress plugin, affecting versions <= 1.89.4. 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 1.89.6; sites on affected versions should update now. Disclosed August 2024, reported by Ananda Dhakal.

Vulnerability Overview

The AFI – The Easiest Integration Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.89.4. This is due to missing or incorrect nonce validation on the adfoin_duplicate_integration() function. This makes it possible for unauthenticated attackers to duplicate an integration via a forged request 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)

Advanced Form Integration <= 1.89.4 carries this weakness at adfoin_duplicate_integration(), and reaching it 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 Advanced Form Integration the fix is 1.89.6: builds <= 1.89.4 are affected, anything from 1.89.6 onward is not.

Remediation

Update to version 1.89.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Advanced Form Integration: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Advanced Form Integration 1.89.6 closes this, and updating the plugin is the step that ends it.
