CVE-2025-39600 Overview
CVE-2025-39600 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the CRM Perks Integration for WooCommerce and QuickBooks WordPress plugin (wp-woocommerce-quickbooks). The flaw impacts all plugin versions up to and including 1.3.1. An attacker can craft a malicious request that, when triggered by an authenticated user visiting an attacker-controlled page, executes unauthorized actions in the WordPress administrative context. The weakness is classified as [CWE-352] and requires user interaction to succeed.
Critical Impact
Successful exploitation lets a remote attacker perform state-changing actions in the plugin without the victim's consent, potentially altering WooCommerce and QuickBooks integration settings.
Affected Products
- CRM Perks Integration for WooCommerce and QuickBooks (wp-woocommerce-quickbooks) versions up to and including 1.3.1
- WordPress sites running WooCommerce with the affected plugin installed
- QuickBooks integration workflows dependent on this plugin

Technical Details for CVE-2025-39600
Vulnerability Analysis
The vulnerability is a Cross-Site Request Forgery issue in the Integration for WooCommerce and QuickBooks plugin. The plugin exposes administrative actions that do not adequately validate the origin or authenticity of incoming requests. An attacker who lures an authenticated site administrator to a malicious page can cause the browser to submit forged requests that the plugin accepts as legitimate.
The scope is limited to actions the targeted user is authorized to perform. Because the vulnerability requires user interaction and only compromises integrity to a limited degree, confidentiality and availability are not directly affected. The EPSS probability of exploitation currently remains low based on the latest scoring.
Root Cause
The root cause is the absence or improper validation of anti-CSRF tokens, commonly implemented in WordPress through wp_nonce_field() and check_admin_referer(). Without token verification, the plugin cannot distinguish requests initiated by an administrator from forged requests submitted by a third-party site while that administrator is logged in.
Attack Vector
Exploitation requires the following conditions:
- A WordPress administrator (or a user with sufficient plugin privileges) must be authenticated to the target site.
- That user must visit an attacker-controlled page or click a crafted link.
- The attacker's page issues a request to a vulnerable plugin endpoint, using the victim's active session cookies.
Because wp-woocommerce-quickbooks handles data synchronization between WooCommerce and QuickBooks, forged requests could tamper with integration configuration or trigger unintended plugin actions. See the Patchstack WordPress Vulnerability advisory for additional technical context.
Detection Methods for CVE-2025-39600
Indicators of Compromise
- Unexpected changes to plugin settings or QuickBooks integration configuration within WordPress
- Administrator sessions generating POST requests with Referer headers pointing to unknown external domains
- Requests to plugin admin endpoints lacking a valid _wpnonce parameter
Detection Strategies
- Review web server access logs for administrative plugin endpoints receiving requests with off-site Referer values.
- Enable WordPress audit logging to record administrative configuration changes and user activity in the plugin.
- Correlate outbound QuickBooks API calls with expected administrative workflow times to detect anomalies.
Monitoring Recommendations
- Monitor the installed version of wp-woocommerce-quickbooks across managed WordPress instances and flag any at 1.3.1 or earlier.
- Alert on administrator account activity originating from unusual referrers or immediately after browsing external sites.
- Track modifications to the plugin's configuration options stored in the wp_options table.
How to Mitigate CVE-2025-39600
Immediate Actions Required
- Upgrade Integration for WooCommerce and QuickBooks to a version later than 1.3.1 once released by CRM Perks.
- Audit recent administrative actions in WordPress for unauthorized configuration changes tied to the plugin.
- Require administrators to log out of WordPress before browsing untrusted sites and to use dedicated browser profiles for admin work.
Patch Information
Refer to the Patchstack advisory for the latest fixed version information. Apply plugin updates through the WordPress dashboard or via WP-CLI as soon as a patched release is available from the vendor.
Workarounds
- Deactivate the wp-woocommerce-quickbooks plugin until a patched version is installed.
- Restrict access to the WordPress admin area using IP allow-lists at the web server or WAF layer.
- Deploy a web application firewall rule to block requests to plugin admin endpoints that lack a valid nonce or arrive with an external Referer header.
# Configuration example: update the plugin via WP-CLI once a fixed version is released
wp plugin update wp-woocommerce-quickbooks
# Or temporarily deactivate the plugin as a workaround
wp plugin deactivate wp-woocommerce-quickbooks
