CVE-2025-24597 Overview
CVE-2025-24597 is a sensitive information disclosure vulnerability in the Barcode Generator for WooCommerce WordPress plugin developed by Dmitry V. (CEO of "UKR Solution"). The plugin, distributed under the slug embedding-barcodes-into-product-pages-and-orders, embeds sensitive data in outbound responses that authenticated low-privilege users can retrieve. The flaw affects all plugin versions up to and including 2.0.2. The issue is tracked under CWE-201: Insertion of Sensitive Information Into Sent Data.
Critical Impact
An authenticated attacker with low privileges can retrieve embedded sensitive data from the WooCommerce store, exposing confidential order or customer information over the network.
Affected Products
- Barcode Generator for WooCommerce plugin versions up to and including 2.0.2
- WordPress sites running the embedding-barcodes-into-product-pages-and-orders plugin
- WooCommerce deployments that rely on this plugin for barcode embedding in products and orders
Discovery Timeline

Technical Details for CVE-2025-24597
Vulnerability Analysis
The Barcode Generator for WooCommerce plugin embeds sensitive information into data sent to clients that should not receive it. Because the plugin does not enforce sufficient authorization checks on the responses it generates, an authenticated user with a low-privilege account can request pages or endpoints that leak protected fields. The exposed data may include order details, customer identifiers, or barcode payloads tied to purchases.
The attack is network-reachable and requires no user interaction. Confidentiality is directly impacted, while integrity and availability remain unaffected. The vulnerability class ([CWE-201]) commonly arises when server-side templates or REST responses include internal fields without filtering based on the requester's role.
Root Cause
The root cause is improper output filtering in the plugin's response generation logic. Data intended for privileged roles is placed into responses served to lower-privileged authenticated users. The plugin does not restrict which fields are serialized based on the caller's capability, resulting in inadvertent disclosure.
Attack Vector
Exploitation requires an authenticated session with low privileges on the target WordPress site. The attacker issues a normal HTTP request to a plugin-served page or endpoint and parses the response for embedded sensitive fields. No specialized tooling or elevated permissions are required, and no user interaction is needed on the victim side.
Because no public proof-of-concept exploit has been published, defenders should refer to the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-24597
Indicators of Compromise
- Unexpected HTTP requests from authenticated low-privilege accounts (subscriber, customer) to plugin-generated pages or WooCommerce order endpoints
- Response payloads returned to non-administrator sessions containing order metadata, customer email addresses, or barcode identifiers
- Repeated enumeration patterns against product or order URLs served by the embedding-barcodes-into-product-pages-and-orders plugin
Detection Strategies
- Inventory WordPress installations and identify sites running the Barcode Generator for WooCommerce plugin at version 2.0.2 or earlier
- Review web server access logs for authenticated non-admin sessions issuing bulk requests to WooCommerce order or product URLs
- Correlate response sizes and content types from plugin endpoints to identify sessions receiving larger-than-expected payloads
Monitoring Recommendations
- Enable WordPress audit logging to record REST API calls and page views by authenticated non-admin users
- Alert on any customer or subscriber account performing sequential access to order-detail resources
- Monitor egress traffic from the WordPress host for abnormal volumes of order or customer data leaving the environment
How to Mitigate CVE-2025-24597
Immediate Actions Required
- Upgrade the Barcode Generator for WooCommerce plugin to a version later than 2.0.2 as soon as a fixed release is published
- Audit user accounts and revoke unnecessary customer or subscriber accounts on affected WooCommerce sites
- Rotate any sensitive identifiers, such as order tokens or barcode payloads, that may have been exposed
Patch Information
A fixed version was not identified in the referenced advisory at the time of publication. Site administrators should consult the Patchstack Vulnerability Report and the plugin vendor's release notes for the most current remediation guidance and apply updates through the WordPress plugin manager.
Workarounds
- Deactivate the Barcode Generator for WooCommerce plugin until a patched version is installed
- Restrict access to WooCommerce order and product endpoints using a web application firewall rule that requires an administrator role
- Disable self-service account registration on the WooCommerce site to reduce the pool of authenticated low-privilege accounts
