At a glance

CVE-2023-23731 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the WishSuite WordPress plugin, affecting versions <= 1.3.3. 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 1.3.4; sites on affected versions should update now. Disclosed March 2023, reported by István Márton.

Vulnerability Overview

The WishSuite plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.3. This is due to missing or incorrect nonce validation on the plugin_activation() function. This makes it possible for unauthenticated attackers to activate arbitrary plugins, 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)

WishSuite <= 1.3.3 carries this weakness at plugin_activation(), 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 WishSuite the fix is 1.3.4: builds <= 1.3.3 are affected, anything from 1.3.4 onward is not.

Remediation

Update to version 1.3.4, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WishSuite: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WishSuite 1.3.4 closes this, and updating the plugin is the step that ends it.
