CVE-2025-58799 Overview
CVE-2025-58799 is a Cross-Site Request Forgery (CSRF) vulnerability in the themelocation Custom WooCommerce Checkout Fields Editor plugin for WordPress. The flaw affects the add-fields-to-checkout-page-woocommerce plugin from unspecified versions through 1.3.4. The vulnerability is tracked under CWE-352: Cross-Site Request Forgery.
An attacker can trick an authenticated administrator into submitting a forged request that modifies checkout field configurations on a WooCommerce store. Exploitation requires user interaction, typically through a malicious link or crafted page loaded by an authenticated user.
Critical Impact
Successful exploitation allows an unauthenticated remote attacker to alter WooCommerce checkout field settings by leveraging an authenticated victim's session, impacting the integrity of store checkout configurations.
Affected Products
- themelocation Custom WooCommerce Checkout Fields Editor plugin (add-fields-to-checkout-page-woocommerce)
- Plugin versions through 1.3.4
- WordPress sites running WooCommerce with the affected plugin installed

Technical Details for CVE-2025-58799
Vulnerability Analysis
The vulnerability stems from missing or improperly implemented CSRF protection in the Custom WooCommerce Checkout Fields Editor plugin. State-changing actions handled by the plugin lack sufficient anti-CSRF tokens, commonly implemented in WordPress through the wp_nonce_field() and check_admin_referer() functions.
Without valid nonce verification, the plugin accepts requests based solely on the presence of an authenticated session cookie. This allows an attacker-hosted page to trigger privileged actions when an administrator visits the malicious content while logged in to WordPress.
The attack complexity is low, and no privileges are required from the attacker. However, user interaction from an authenticated victim is mandatory for exploitation to succeed.
Root Cause
The root cause is the absence of proper CSRF token validation on plugin endpoints that modify checkout field configuration data. WordPress provides built-in nonce mechanisms to prevent CSRF, but the plugin either omits nonce generation on forms or fails to validate submitted nonces on the server side before performing state changes.
Attack Vector
An attacker crafts a malicious HTML page or link containing a forged request targeting the vulnerable plugin endpoint. When an authenticated WordPress administrator visits the attacker-controlled page, the browser automatically attaches session cookies and submits the request to the target WooCommerce site.
The request executes with the administrator's privileges, allowing modification of checkout fields. This can be leveraged to inject unwanted fields, remove required fields, or otherwise disrupt the checkout process. Refer to the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-58799
Indicators of Compromise
- Unexpected modifications to WooCommerce checkout field configurations that do not correlate with legitimate administrator activity
- HTTP referer headers on plugin administrative requests pointing to external, untrusted domains
- Administrator sessions submitting POST requests to plugin endpoints without corresponding admin panel navigation in access logs
Detection Strategies
- Monitor WordPress audit logs for changes to checkout field settings, correlating changes with administrator browsing activity
- Inspect web server access logs for POST requests to the plugin's admin endpoints originating from suspicious referers or lacking expected referer values
- Deploy web application firewall (WAF) rules that flag requests to WooCommerce plugin admin actions without valid WordPress nonces
Monitoring Recommendations
- Enable a WordPress activity logging plugin to record configuration changes with user, IP, and timestamp attribution
- Alert on administrator account activity from unusual geolocations or user-agent strings
- Review plugin configuration weekly against a known-good baseline to detect unauthorized changes
How to Mitigate CVE-2025-58799
Immediate Actions Required
- Identify all WordPress installations running the Custom WooCommerce Checkout Fields Editor plugin at version 1.3.4 or earlier
- Update the plugin to a patched release once the vendor publishes a fix that adds nonce verification
- Restrict administrator browsing habits to avoid clicking untrusted links while logged in to WordPress
Patch Information
At the time of publication, the vulnerability affects versions up to and including 1.3.4. Consult the Patchstack Vulnerability Report and the plugin's WordPress.org page for the latest patch availability.
Workarounds
- Deactivate and remove the Custom WooCommerce Checkout Fields Editor plugin until a patched version is available
- Deploy a web application firewall rule that blocks requests to plugin admin endpoints lacking a valid WordPress nonce parameter
- Enforce administrator use of a dedicated browser or browser profile for WordPress management to reduce cross-site request exposure
- Require re-authentication for sensitive administrative actions using a plugin such as WordPress two-factor authentication
