CVE-2025-22667: WooCommerce Export Plugin Auth Bypass Flaw

CVE-2025-22667 Overview

CVE-2025-22667 is a Missing Authorization vulnerability [CWE-862] in the Creative Werk Designs "Export Order, Product, Customer & Coupon for WooCommerce to Google Sheets" plugin (wpsyncsheets-woocommerce) for WordPress. The flaw affects all versions from an unspecified initial release through 1.8.2. An authenticated attacker with low privileges can invoke plugin functionality that lacks proper capability checks, resulting in unauthorized access to protected actions over the network. The vulnerability was cataloged by Patchstack and published to the National Vulnerability Database (NVD) on March 27, 2025.

Critical Impact

Authenticated users with low privileges can bypass access controls on the plugin, exposing WooCommerce export operations to unauthorized manipulation.

Affected Products

• Creative Werk Designs Export Order, Product, Customer & Coupon for WooCommerce to Google Sheets (wpsyncsheets-woocommerce)
• All plugin versions up to and including 1.8.2
• WordPress sites running WooCommerce with this plugin installed

Technical Details for CVE-2025-22667

Vulnerability Analysis

The vulnerability stems from a broken access control condition in the wpsyncsheets-woocommerce plugin. Plugin endpoints intended for administrative use fail to verify the acting user's capabilities before executing the requested action. An attacker who holds any authenticated session with low-tier permissions can reach these endpoints and trigger functionality reserved for higher-privileged roles. The scope is limited to integrity impact, meaning the flaw allows unauthorized modification or invocation of plugin actions rather than direct data exfiltration or service disruption.

Root Cause

The root cause is a missing authorization check, classified under CWE-862. Handler functions inside the plugin do not call WordPress capability APIs such as current_user_can() before executing privileged logic. Nonce verification alone, if present, is insufficient because it protects against cross-site request forgery but does not enforce role-based authorization.

Attack Vector

Exploitation requires network access to the WordPress site and a valid low-privileged account, such as a subscriber or customer role commonly provisioned in WooCommerce storefronts. The attacker sends an authenticated HTTP request to the vulnerable plugin endpoint. Because no capability check is enforced, the request executes with the same effect as if issued by an authorized administrator. No user interaction is required beyond the attacker's own request. For technical specifics, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-22667

Indicators of Compromise

• Unexpected authenticated requests to wpsyncsheets-woocommerce plugin endpoints from accounts that hold subscriber or customer roles.
• WooCommerce export or sync operations initiated outside of scheduled administrative windows.
• New or modified Google Sheets integration configurations without a corresponding administrator action in the audit trail.

Detection Strategies

• Review WordPress access logs for POST or AJAX requests targeting admin-ajax.php with action parameters referencing wpsyncsheets handlers originating from non-administrative sessions.
• Correlate WooCommerce order and customer export events with the acting user's role assignment to flag capability mismatches.
• Enumerate installed plugins on managed WordPress hosts and identify instances of wpsyncsheets-woocommerce at version 1.8.2 or earlier.

Monitoring Recommendations

• Enable verbose logging on WordPress and forward events to a centralized log platform for role-based anomaly analysis.
• Alert on privilege boundary crossings where low-privileged accounts trigger plugin actions typically performed by administrators.
• Monitor outbound connections to Google Sheets APIs from the WordPress host for unexpected export activity.

How to Mitigate CVE-2025-22667

Immediate Actions Required

• Identify all WordPress installations running wpsyncsheets-woocommerce version 1.8.2 or earlier.
• Update the plugin to a version later than 1.8.2 once released by Creative Werk Designs, per the vendor advisory tracked in Patchstack.
• Audit existing user accounts and remove unnecessary low-privileged accounts that could be leveraged for exploitation.

Patch Information

At the time of NVD publication, the advisory lists the affected range as "from n/a through <= 1.8.2." Consult the Patchstack Vulnerability Report for the current fixed version and apply the update through the WordPress plugin manager or WP-CLI.

Workarounds

• Deactivate the wpsyncsheets-woocommerce plugin until a patched release is installed.
• Restrict access to admin-ajax.php endpoints associated with the plugin using a web application firewall (WAF) rule that filters by action parameter and user role.
• Disable open user registration on WooCommerce sites where customer accounts are not required, reducing the pool of low-privileged accounts an attacker could abuse.

# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate wpsyncsheets-woocommerce
wp plugin status wpsyncsheets-woocommerce
