CVE-2025-48249 Overview
CVE-2025-48249 is a stored cross-site scripting (XSS) vulnerability in the WPFactory EAN for WooCommerce plugin (ean-for-woocommerce) for WordPress. The flaw affects all plugin versions up to and including 5.4.6. Authenticated attackers with low privileges can inject persistent JavaScript payloads that execute in the browsers of users who view the affected pages. The vulnerability is tracked under CWE-79 for improper neutralization of input during web page generation. See the Patchstack XSS Vulnerability Advisory for advisory details.
Critical Impact
Attackers can persistently inject malicious scripts into WooCommerce store pages, enabling session hijacking, credential theft, and administrative account takeover through victim interaction.
Affected Products
- WPFactory EAN for WooCommerce plugin versions through 5.4.6
- WordPress sites running WooCommerce with the ean-for-woocommerce extension
- Any storefront exposing product management interfaces to lower-privileged users

Technical Details for CVE-2025-48249
Vulnerability Analysis
The EAN for WooCommerce plugin fails to properly neutralize user-supplied input before rendering it in web pages. This deficiency permits stored cross-site scripting through EAN-related product fields the plugin exposes. Injected payloads persist in the WordPress database and execute whenever an administrator, shop manager, or customer loads an affected view.
Exploitation requires the attacker to hold a low-privileged authenticated account and needs a victim to load the compromised page. The scope change indicates the injected script can affect resources beyond the vulnerable component, including the WordPress administrative interface. Successful exploitation can lead to session cookie theft, forced administrative actions, and delivery of secondary payloads to store visitors.
Root Cause
The root cause is missing output encoding and input sanitization when the plugin renders EAN product metadata. Values submitted through plugin fields are stored verbatim and later emitted into HTML contexts without escaping via functions such as esc_html(), esc_attr(), or wp_kses_post(). This allows <script> tags and event-handler attributes to survive the render path.
Attack Vector
An authenticated attacker with contributor or shop-manager level access submits a crafted payload into a plugin-managed field, such as an EAN barcode value tied to a product. The malicious content is stored in the WordPress database. When another user, typically an administrator reviewing the product listing, loads the page, the browser executes the payload in the site's origin. This enables cookie exfiltration, CSRF against WordPress REST endpoints, and account takeover.
No verified public exploit code is available for this vulnerability. Refer to the Patchstack advisory for technical details.
Detection Methods for CVE-2025-48249
Indicators of Compromise
- Presence of <script>, onerror=, onload=, or javascript: strings in wp_postmeta rows tied to EAN plugin meta keys.
- Unexpected outbound requests from administrator browsers to attacker-controlled domains shortly after loading product edit pages.
- New administrator accounts or altered user roles created immediately after an admin session viewed a product with an EAN field.
Detection Strategies
- Query the WordPress database for EAN meta values containing HTML tags or JavaScript event handlers.
- Deploy a Web Application Firewall (WAF) rule to inspect POST requests to admin.php and WooCommerce product endpoints for XSS payload patterns.
- Enable Content Security Policy (CSP) violation reporting to surface script executions from unexpected origins on the WordPress admin interface.
Monitoring Recommendations
- Audit WordPress activity logs for product edits by contributor and shop-manager accounts.
- Monitor authentication logs for anomalous administrator session activity following product page views.
- Track plugin version drift across all WordPress installations to identify hosts still exposed to versions at or below 5.4.6.
How to Mitigate CVE-2025-48249
Immediate Actions Required
- Update the EAN for WooCommerce plugin to a version above 5.4.6 as soon as the vendor publishes a patched release.
- Review all low-privileged WordPress accounts and remove any that are unused or unnecessary.
- Scan wp_postmeta for existing malicious payloads and sanitize any stored EAN values.
Patch Information
The vendor advisory tracked at Patchstack documents the vulnerability in versions through 5.4.6. Administrators should apply the vendor-supplied fix once available and validate the plugin version reported in the WordPress dashboard matches the patched release.
Workarounds
- Deactivate the EAN for WooCommerce plugin until a patched version is installed.
- Restrict product editing capabilities so only trusted administrator accounts can modify EAN fields.
- Deploy a WAF signature that blocks HTML tags and JavaScript event handlers in WooCommerce product metadata submissions.
