At a glance
CVE-2023-41651 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Multi-column Tag Map WordPress plugin, affecting versions <= 17.0.26. 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 17.0.27; sites on affected versions should update now. Disclosed September 2023, reported by Rio Darmawan.
Vulnerability Overview
The Multi-column Tag Map plugin for WordPress is vulnerable to Cross-Site Request Forgery due to a missing nonce check on the sc_mcTagMap_plugin_options() function in versions up to, and including, 17.0.26. This makes it possible for unauthenticated attackers to update the plugin's setting, via a forged request granted they can trick the site's 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)
Multi-column Tag Map <= 17.0.26 carries this weakness at sc_mcTagMap_plugin_options(), 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 Multi-column Tag Map the fix is 17.0.27: builds <= 17.0.26 are affected, anything from 17.0.27 onward is not.
Remediation
Update to version 17.0.27, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Multi-column Tag Map: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Multi-column Tag Map 17.0.27 closes this, and updating the plugin is the step that ends it.
