CVE-2025-14001: WP Duplicate Page Auth Bypass Vulnerability

CVE-2025-14001 Overview

The WP Duplicate Page plugin for WordPress contains a critical authorization bypass vulnerability that allows authenticated attackers to duplicate arbitrary content without proper authorization. The vulnerability exists due to missing capability checks on the duplicateBulkHandle and duplicateBulkHandleHPOS functions in all versions up to and including 1.8.

This Missing Authorization vulnerability (CWE-862) enables attackers with Contributor-level access or higher to bypass the plugin's "Allowed User Roles" setting. Even when a user's role is explicitly excluded from duplication privileges, they can still exploit these unprotected functions to duplicate posts, pages, and WooCommerce HPOS (High-Performance Order Storage) orders.

Critical Impact

Authenticated attackers can duplicate WooCommerce orders, potentially exposing sensitive customer information and enabling duplicate fulfillment of orders, leading to financial losses and data breaches.

Affected Products

• WP Duplicate Page plugin for WordPress versions up to and including 1.8
• WordPress sites using WooCommerce with HPOS enabled
• Any WordPress installation with the vulnerable plugin and user accounts at Contributor level or above

Technical Details for CVE-2025-14001

Vulnerability Analysis

This vulnerability is classified as Missing Authorization (CWE-862), where the affected functions fail to verify whether the requesting user has the necessary capabilities to perform duplication operations. The attack can be executed over the network without requiring user interaction, and requires only low-privilege authentication (Contributor-level access).

The vulnerability affects two specific functions within the ButtonDuplicate.php class:

• duplicateBulkHandle - handles bulk duplication of standard WordPress posts and pages
• duplicateBulkHandleHPOS - handles bulk duplication of WooCommerce High-Performance Order Storage orders

Both functions process duplication requests without validating whether the authenticated user's role is authorized to perform such actions, effectively bypassing the plugin's built-in access control configuration.

Root Cause

The root cause of this vulnerability is the absence of proper capability checks within the duplicateBulkHandle and duplicateBulkHandleHPOS functions. While the plugin provides an "Allowed User Roles" setting that administrators can configure to restrict duplication privileges, this setting is not enforced at the function level. The vulnerable code at lines 54 and 79 of ButtonDuplicate.php processes requests without verifying the user's authorization status against the plugin's configured role restrictions.

Attack Vector

The attack requires network access and authentication with at least Contributor-level privileges on the target WordPress site. An attacker can exploit this vulnerability by directly invoking the vulnerable bulk duplication functions, even if their user role has been explicitly excluded from the plugin's allowed roles configuration.

The exploitation flow involves:

1. Attacker authenticates to WordPress with a Contributor or higher-level account
2. Attacker identifies the target posts, pages, or WooCommerce orders to duplicate
3. Attacker crafts requests to invoke duplicateBulkHandle or duplicateBulkHandleHPOS directly
4. The functions execute without checking role restrictions, creating unauthorized duplicates
5. For WooCommerce orders, this can expose customer data and enable duplicate order fulfillment

Detection Methods for CVE-2025-14001

Indicators of Compromise

• Unexpected duplicate posts, pages, or WooCommerce orders appearing in the WordPress database
• Audit logs showing bulk duplication actions performed by users not authorized for such operations
• Multiple WooCommerce orders with identical content but different order IDs created in rapid succession
• Activity logs showing API calls to duplication endpoints from low-privilege user accounts

Detection Strategies

• Monitor WordPress activity logs for duplication events initiated by users outside the configured "Allowed User Roles" setting
• Implement database monitoring to detect rapid creation of duplicate content entries
• Review WooCommerce order logs for unexpected duplicate orders that could indicate exploitation
• Deploy web application firewalls (WAF) with rules to detect and block suspicious bulk operation requests

Monitoring Recommendations

• Enable comprehensive audit logging for all WordPress content creation and modification events
• Configure alerts for WooCommerce order duplication events, especially those triggered by non-administrative users
• Regularly review user activity reports for Contributor-level accounts performing unusual operations
• Implement real-time monitoring for database write operations that create duplicate records

How to Mitigate CVE-2025-14001

Immediate Actions Required

• Update the WP Duplicate Page plugin to a patched version immediately (versions above 1.8)
• Review recent content duplication activity for signs of exploitation
• Audit WooCommerce orders for any unauthorized duplicates that may have been created
• Temporarily disable the plugin if immediate patching is not possible

Patch Information

The vulnerability has been addressed in the WordPress plugin changeset 3432233. Site administrators should update to the latest version of WP Duplicate Page through the WordPress plugin repository. The patch implements proper capability checks on the duplicateBulkHandle and duplicateBulkHandleHPOS functions to enforce the "Allowed User Roles" configuration.

For additional technical details and vulnerability tracking, refer to the Wordfence Vulnerability Report.

Workarounds

• Disable the WP Duplicate Page plugin until the update can be applied
• Restrict Contributor-level access to trusted users only until the vulnerability is patched
• Implement a WordPress security plugin with capability monitoring to detect unauthorized function calls
• For WooCommerce sites, enable additional order validation to prevent duplicate fulfillment

# Temporarily disable the vulnerable plugin via WP-CLI
wp plugin deactivate wp-duplicate-page

# Update to the patched version
wp plugin update wp-duplicate-page

# Verify the update was successful
wp plugin status wp-duplicate-page
