CVE-2025-54674: WooCommerce Product Configurator CSRF Flaw

CVE-2025-54674 Overview

CVE-2025-54674 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Product Configurator for WooCommerce WordPress plugin developed by mklacroix. The flaw exists in all plugin versions up to and including 1.4.4. An attacker can craft a malicious web page that, when visited by an authenticated WordPress user, triggers unauthorized state-changing actions within the plugin. The issue is tracked under CWE-352: Cross-Site Request Forgery. Exploitation requires user interaction, such as clicking a crafted link or visiting an attacker-controlled page while authenticated to the target WordPress site.

Critical Impact
Successful exploitation allows attackers to perform unauthorized plugin actions on behalf of authenticated WordPress users, resulting in limited integrity and availability impact on the affected WooCommerce store.

Affected Products

mklacroix Product Configurator for WooCommerce plugin (product-configurator-for-woocommerce)
All versions from initial release through 1.4.4
WordPress sites running WooCommerce with the affected plugin installed

Technical Details for CVE-2025-54674

Vulnerability Analysis

The vulnerability stems from missing or improperly implemented anti-CSRF protections in the Product Configurator for WooCommerce plugin. WordPress provides a nonce mechanism (wp_nonce_field, check_admin_referer, wp_verify_nonce) to validate that state-changing requests originate from legitimate users. When these checks are absent or improperly validated, attackers can forge requests that the target's browser will submit with valid session cookies.

The attack requires user interaction, meaning the victim must be tricked into visiting a malicious page or clicking a crafted link while authenticated. The scope is unchanged, and the impact is limited to integrity and availability with no direct confidentiality exposure. This aligns with typical CSRF weaknesses classified under CWE-352.

Root Cause

The root cause is the plugin's failure to enforce a validated, request-specific nonce token on one or more sensitive endpoints. Without a bound nonce, the plugin cannot distinguish between a legitimate action initiated by the user through the WordPress admin interface and a forged request submitted from an external origin.

Attack Vector

An attacker hosts a malicious page containing a hidden form or JavaScript that automatically issues an HTTP request to the vulnerable plugin endpoint on the target WordPress site. When an authenticated administrator or privileged user visits the attacker's page, the browser attaches the session cookies to the forged request. The plugin processes the request as if it originated from the legitimate user. Refer to the Patchstack WordPress Vulnerability Report for full technical context.

No verified public proof-of-concept code is available for this CVE. The exploitation pattern follows standard WordPress CSRF techniques against endpoints that lack nonce validation.

Detection Methods for CVE-2025-54674

Indicators of Compromise

Unexpected changes to product configurator settings, options, or configurations within WooCommerce
HTTP POST requests to plugin endpoints containing an Origin or Referer header that does not match the site's domain
Requests to plugin action handlers missing the _wpnonce parameter or with invalid nonce values
Administrative activity in WordPress logs correlated with users viewing external links or emails

Detection Strategies

Enable WordPress audit logging plugins to capture all administrative and plugin-level changes with user, timestamp, and source IP attribution
Review web server access logs for POST requests to product-configurator-for-woocommerce endpoints with suspicious Referer headers
Deploy a Web Application Firewall (WAF) with rules that flag cross-origin state-changing requests to WordPress admin URLs
Correlate plugin configuration changes with user session activity to identify unauthorized modifications

Monitoring Recommendations

Monitor the wp-admin/admin-ajax.php and wp-admin/admin-post.php endpoints for requests lacking valid nonce tokens
Alert on anomalous administrator actions occurring outside expected working hours or from unusual IP addresses
Track plugin version inventory across WordPress deployments to identify unpatched installations of product-configurator-for-woocommerce

How to Mitigate CVE-2025-54674

Immediate Actions Required

Identify all WordPress installations running the Product Configurator for WooCommerce plugin at version 1.4.4 or earlier
Update the plugin to a patched version once released by the vendor mklacroix
If a patched version is not yet available, deactivate and remove the plugin until a fix is published
Review recent WooCommerce product configurator settings and audit logs for unauthorized changes

Patch Information

At the time of publication, the vulnerability affects all versions of product-configurator-for-woocommerce from n/a through 1.4.4. Administrators should consult the Patchstack WordPress Vulnerability Report and the plugin's WordPress.org listing for updated release information.

Workarounds

Deploy a Web Application Firewall (WAF) with CSRF protection rules to block cross-origin state-changing requests to WordPress admin endpoints
Enforce SameSite=Strict or SameSite=Lax cookie attributes on WordPress session cookies to reduce CSRF exposure
Instruct administrative users to log out of WordPress when not actively managing the site and avoid clicking untrusted links while authenticated
Restrict WordPress admin access by source IP address using server-level controls where operationally feasible

bash

# Example nginx configuration to restrict wp-admin access by source IP
location ~ ^/wp-admin/ {
    allow 203.0.113.0/24;   # Trusted admin network
    deny all;
}
