CVE-2025-68834 Overview
CVE-2025-68834 is a missing authorization vulnerability in the Sync Master Sheet – Product Sync with Google Sheet for WooCommerce plugin developed by Saiful Islam. The flaw affects all plugin versions up to and including 1.1.3. It results from incorrectly configured access control on plugin functionality, allowing unauthenticated attackers to invoke privileged actions over the network. The issue is tracked under CWE-862: Missing Authorization and impacts the integrity of WooCommerce product data synchronized through the plugin.
Critical Impact
Unauthenticated network attackers can abuse missing authorization checks to manipulate WooCommerce product data on affected sites running the plugin up to version 1.1.3.
Affected Products
- Sync Master Sheet – Product Sync with Google Sheet for WooCommerce (product-sync-master-sheet)
- All versions from initial release through 1.1.3
- WordPress sites running WooCommerce with this plugin installed

Technical Details for CVE-2025-68834
Vulnerability Analysis
The vulnerability stems from missing authorization checks on plugin endpoints that handle product synchronization between WooCommerce and Google Sheets. The plugin exposes functionality without verifying the caller's capability or role. Attackers can reach these endpoints over the network without authentication or user interaction. Successful exploitation compromises the integrity of WooCommerce product records, including titles, prices, stock levels, and metadata synchronized through the plugin.
The weakness is classified as CWE-862 Missing Authorization. The plugin fails to enforce role or capability verification before executing sensitive sync operations. According to the Patchstack WordPress Vulnerability Report, the issue is categorized as broken access control affecting the plugin through version 1.1.3.
Root Cause
The root cause is the absence of capability checks such as current_user_can() and nonce validation via check_admin_referer() or check_ajax_referer() on plugin action handlers. WordPress plugins must validate both authentication state and authorization scope before executing privileged operations. The Sync Master Sheet plugin registers handlers that execute product sync logic without these guards.
Attack Vector
An unauthenticated remote attacker sends crafted HTTP requests to the vulnerable plugin endpoints exposed by the WordPress site. No credentials, user interaction, or elevated privileges are required. The attack vector is network-based and the attack complexity is low. The vulnerability impacts integrity by enabling unauthorized modification of product data synchronized through the plugin.
No verified public proof-of-concept code is available at this time. Refer to the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-68834
Indicators of Compromise
- Unexpected modifications to WooCommerce product titles, prices, descriptions, or stock quantities without corresponding administrator activity in WordPress audit logs.
- HTTP requests to product-sync-master-sheet plugin endpoints originating from unauthenticated sessions or unfamiliar IP addresses.
- New or altered entries in the wp_posts and wp_postmeta tables affecting WooCommerce product post types outside scheduled sync windows.
Detection Strategies
- Review web server access logs for POST or GET requests to URLs containing product-sync-master-sheet or related AJAX action parameters such as admin-ajax.php?action= referencing plugin functions.
- Correlate WordPress user session data with product modification events to identify changes performed without an authenticated administrator session.
- Enable WordPress audit logging plugins to capture product CRUD operations and flag changes lacking an associated logged-in user.
Monitoring Recommendations
- Monitor the WordPress wp-content/plugins/product-sync-master-sheet/ directory for file integrity changes and unexpected file additions.
- Alert on outbound connections from the WordPress host to unknown Google Sheets API endpoints not configured by administrators.
- Track HTTP response codes from plugin endpoints and investigate sudden volume increases in successful 200 responses to unauthenticated callers.
How to Mitigate CVE-2025-68834
Immediate Actions Required
- Update the Sync Master Sheet – Product Sync with Google Sheet for WooCommerce plugin to a version newer than 1.1.3 once the vendor releases a patched build.
- If no patched version is available, deactivate and remove the plugin from all affected WordPress installations until a fix is published.
- Audit WooCommerce product data for unauthorized modifications and restore from clean backups where tampering is identified.
Patch Information
At the time of CVE publication, the vulnerability affects all versions through 1.1.3. Administrators should consult the Patchstack advisory and the WordPress plugin repository for patched releases and apply updates as soon as they become available.
Workarounds
- Restrict access to wp-admin/admin-ajax.php and plugin-specific endpoints using web application firewall (WAF) rules that require authenticated sessions.
- Apply IP allowlisting at the reverse proxy or hosting layer to limit access to plugin endpoints to known administrative IP addresses.
- Disable the plugin entirely until a fixed version is released if Google Sheets synchronization is not business-critical.
# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate product-sync-master-sheet
