CVE-2025-22673 Overview
CVE-2025-22673 is a missing authorization vulnerability in the WPFactory EAN for WooCommerce plugin (ean-for-woocommerce) for WordPress. The flaw exists in all versions up to and including 5.3.5. The plugin fails to enforce access control checks on protected functionality, allowing authenticated users with low privileges to invoke actions that should require elevated permissions. The issue is categorized under CWE-862: Missing Authorization and stems from incorrectly configured access control security levels within the plugin's request handlers.
Critical Impact
Authenticated attackers with minimal privileges can access plugin functionality restricted to higher-privileged roles, leading to unauthorized information disclosure within WooCommerce stores.
Affected Products
- WPFactory EAN for WooCommerce (ean-for-woocommerce) plugin versions from n/a through 5.3.5
- WordPress sites running WooCommerce with the vulnerable plugin installed
- Any e-commerce deployment relying on this plugin for EAN barcode management

Technical Details for CVE-2025-22673
Vulnerability Analysis
The WPFactory EAN for WooCommerce plugin extends WooCommerce with European Article Number (EAN) barcode generation and product identification capabilities. The vulnerability exists because the plugin registers request handlers without validating that the calling user holds the required WordPress capability for the requested action. An authenticated user with a low-privilege role, such as subscriber or customer, can invoke protected functionality by sending a crafted request directly to the plugin endpoint.
Exploitation requires network access to the WordPress admin-ajax or REST API endpoint and a valid authenticated session. No user interaction is required beyond the attacker's own request. The impact is limited to confidentiality, allowing unauthorized read access to protected data exposed by the affected handlers.
Root Cause
The root cause is the absence of current_user_can() capability checks on plugin action handlers. The plugin verifies authentication but does not verify authorization, treating any logged-in user as eligible to invoke administrative functions. This is a classic broken access control pattern documented in CWE-862 and highlighted in the Patchstack advisory.
Attack Vector
An attacker registers or authenticates as a low-privilege WordPress user on a site running the vulnerable plugin. The attacker then sends an HTTP request to the plugin's action endpoint, invoking functionality intended for shop managers or administrators. Because the plugin does not validate role or capability, the request executes successfully and returns data or triggers state the attacker should not have access to.

Stop Identity AttacksDetection Methods for CVE-2025-22673
Indicators of Compromise
- Requests to wp-admin/admin-ajax.php or plugin REST endpoints containing ean-for-woocommerce action parameters originating from low-privilege user sessions
- Unexpected access to product EAN metadata by accounts holding only subscriber or customer roles
- Anomalous spikes in authenticated requests to plugin handlers outside normal shop-management workflows
Detection Strategies
- Inventory WordPress installations and identify sites running ean-for-woocommerce version 5.3.5 or earlier
- Review WooCommerce and WordPress access logs for authenticated requests to plugin endpoints from non-administrative accounts
- Correlate user role assignments with actions logged against plugin handlers to surface authorization mismatches
Monitoring Recommendations
- Enable WordPress audit logging to capture plugin action invocations with the calling user and role
- Forward web server logs to a centralized analytics platform such as Singularity Data Lake for correlation across sites
- Alert on POST requests to admin-ajax.php with action parameters referencing the plugin from sessions belonging to low-privilege roles
How to Mitigate CVE-2025-22673
Immediate Actions Required
- Update the WPFactory EAN for WooCommerce plugin to a version released after 5.3.5 that addresses the missing authorization check
- Audit existing WordPress user accounts and remove or disable unused low-privilege accounts that could be leveraged for exploitation
- Review WooCommerce customer registration settings and disable open registration where not required
Patch Information
A fixed version resolving the missing authorization check should be installed by upgrading past 5.3.5. Refer to the Patchstack Vulnerability Report for the vendor's remediation guidance and updated release information.
Workarounds
- Deactivate the ean-for-woocommerce plugin until an updated version is applied
- Deploy a web application firewall rule to block unauthenticated and low-privilege access to plugin action endpoints
- Restrict WooCommerce customer accounts from accessing wp-admin endpoints they do not require for checkout functionality
# Example: identify the installed plugin version via WP-CLI
wp plugin get ean-for-woocommerce --field=version
# Update the plugin to the latest available release
wp plugin update ean-for-woocommerce
# Temporary mitigation: deactivate until patched
wp plugin deactivate ean-for-woocommerce
