At a glance

CVE-2026-6451 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Plugin WordPress plugin, affecting versions <= 1.0.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2026, reported by Régis SENET.

Vulnerability Overview

The cms-fuer-motorrad-werkstaetten plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.0.0. This is due to missing nonce validation on all eight AJAX deletion handlers: vehicles_cfmw_d_vehicle, contacts_cfmw_d_contact, suppliers_cfmw_d_supplier, receipts_cfmw_d_receipt, positions_cfmw_d_position, catalogs_cfmw_d_article, stock_cfmw_d_item, and settings_cfmw_d_catalog. None of these handlers call check_ajax_referer() or wp_verify_nonce(), nor do they perform any capability checks via current_user_can(). This makes it possible for unauthenticated attackers to delete arbitrary vehicles, contacts, suppliers, receipts, positions, catalog articles, stock items, or entire supplier catalogs via a forged request, provided they can trick a logged-in user into performing an action such as clicking a link to a malicious page.

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)

Plugin <= 1.0.0 carries this weakness at check_ajax_referer(), 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. No fixed build of this plugin is recorded for Plugin yet, so installs running <= 1.0.0 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

The attempt arrives as an ordinary request to Plugin: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
