CVE-2025-54030: WooCommerce Google Sheet Connector CSRF

CVE-2025-54030 Overview

CVE-2025-54030 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the WesternDeal WooCommerce Google Sheet Connector plugin for WordPress. The flaw exists in the wc-gsheetconnector plugin in all versions up to and including 1.3.20. The vulnerability is categorized under [CWE-352] (Cross-Site Request Forgery) and allows an attacker to trick an authenticated user into performing unintended state-changing actions on the affected WordPress site. Exploitation requires user interaction, typically by luring a logged-in administrator to visit an attacker-controlled page.

Critical Impact
Successful exploitation can allow attackers to alter plugin configuration or trigger unauthorized actions in the context of an authenticated WooCommerce administrator, potentially disrupting Google Sheet synchronization for order data.

Affected Products

WesternDeal WooCommerce Google Sheet Connector plugin for WordPress
All versions from n/a through 1.3.20
WordPress sites running WooCommerce with the wc-gsheetconnector plugin installed

Technical Details for CVE-2025-54030

Vulnerability Analysis

The vulnerability stems from missing or insufficient CSRF protections in the WooCommerce Google Sheet Connector plugin. WordPress plugins typically defend against CSRF by validating nonces via wp_verify_nonce() or check_admin_referer() on state-changing requests. The affected plugin fails to enforce this validation on one or more privileged endpoints, allowing forged requests to be processed as legitimate administrative actions.

An attacker exploiting this weakness crafts a malicious page or link that submits a request to the target WordPress site. If a logged-in administrator visits the attacker's content, the browser attaches valid session cookies to the forged request. The plugin then executes the action without confirming the request originated from an authorized workflow.

The issue is limited to integrity impact, meaning attackers cannot directly read protected data or fully disrupt site availability through this flaw alone. However, integrity changes can cascade into broader operational issues, including corrupted order-to-sheet synchronization.

Root Cause

The root cause is the absence of anti-CSRF token validation on sensitive plugin actions. Without a nonce check, the plugin cannot distinguish between a legitimate request initiated by an administrator and a forged request triggered by a third-party site.

Attack Vector

The attack is delivered over the network and requires user interaction. An attacker hosts a page containing an auto-submitting form or crafted image tag that targets a vulnerable endpoint of the plugin. When an authenticated WordPress administrator loads the page, the browser transmits the forged request with valid session cookies, executing the action server-side. No verified proof-of-concept code is publicly available. See the Patchstack CSRF Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-54030

Indicators of Compromise

Unexpected changes to WooCommerce Google Sheet Connector plugin settings not initiated by an administrator
HTTP POST requests to wc-gsheetconnector plugin endpoints originating from external Referer headers
Administrative actions logged during periods when no administrator was actively working in the WordPress dashboard

Detection Strategies

Inspect web server access logs for requests to plugin admin endpoints with off-site Referer values or missing nonce parameters
Enable WordPress audit logging to capture configuration changes attributable to the wc-gsheetconnector plugin
Correlate administrator browser activity with plugin state changes to identify actions triggered outside legitimate sessions

Monitoring Recommendations

Monitor WordPress wp-admin request patterns for anomalous cross-origin submissions targeting the vulnerable plugin
Alert on plugin configuration modifications outside change-control windows
Track outbound Google Sheets API activity from the WooCommerce host for unexpected schema or credential changes

How to Mitigate CVE-2025-54030

Immediate Actions Required

Update the WooCommerce Google Sheet Connector plugin to a version later than 1.3.20 as soon as the vendor publishes a fix
Restrict WordPress administrator sessions to trusted browsers and require re-authentication for privileged actions
Educate administrators to avoid clicking untrusted links while logged into the WordPress dashboard

Patch Information

At the time of publication, the advisory identifies versions through 1.3.20 as affected. Consult the Patchstack CSRF Vulnerability Report for the latest fixed version information from the vendor.

Workarounds

Temporarily deactivate the WooCommerce Google Sheet Connector plugin until a patched version is installed
Deploy a Web Application Firewall (WAF) rule that blocks requests to wc-gsheetconnector admin endpoints lacking a valid same-origin Referer header
Enforce strict SameSite=Lax or SameSite=Strict cookie attributes on WordPress authentication cookies to reduce CSRF exposure
Limit the number of accounts holding the WordPress administrator role to reduce the attack surface

bash

# Example WAF rule concept: block cross-origin POSTs to the vulnerable plugin
# Adapt to your WAF syntax (ModSecurity example)
SecRule REQUEST_URI "@contains /wp-admin/admin.php" \
  "chain,phase:2,deny,status:403,id:1054030,msg:'Block cross-origin request to wc-gsheetconnector'"
  SecRule ARGS:page "@streq gsheetconnector" "chain"
  SecRule REQUEST_HEADERS:Referer "!@beginsWith https://your-site.example.com"
