CVE-2026-88929 Overview
CVE-2026-88929 is an information disclosure vulnerability in the Product Badge, Label, Countdown Timer for WooCommerce WordPress plugin versions before 7.5.2. The plugin fails to verify a product's publication status before returning product details through its endpoint. Unauthenticated attackers can read the title, description, and price of draft, pending, and private WooCommerce products. The flaw is categorized under [CWE-200] (Exposure of Sensitive Information to an Unauthorized Actor).
Store operators frequently use draft and private products to stage upcoming launches, price changes, or restricted merchandise. Exposing this data enables competitive intelligence gathering and premature disclosure of business decisions.
Critical Impact
Unauthenticated remote attackers can enumerate non-public WooCommerce product data, including unpublished pricing and product descriptions, without any user interaction.
Affected Products
- Product Badge, Label, Countdown Timer for WooCommerce WordPress plugin versions prior to 7.5.2
- WordPress sites running WooCommerce with the affected plugin installed
- E-commerce environments exposing plugin endpoints to unauthenticated visitors

Technical Details for CVE-2026-88929
Vulnerability Analysis
The plugin exposes a request handler that returns product metadata based on a supplied product identifier. The handler retrieves the product record and serializes its title, description, and price into the response. It does not check the post_status of the requested product before returning data.
WordPress uses statuses such as publish, draft, pending, and private to control visibility. Only products with the publish status are meant to appear to anonymous visitors. Skipping this check turns the endpoint into an enumeration primitive across the entire product catalog.
Because the endpoint is reachable without authentication, an attacker can iterate through product IDs and harvest details for every product regardless of state. The disclosure is limited to non-sensitive fields per the plugin's data model, but includes pricing and descriptive content intended to remain internal.
Root Cause
The root cause is a missing authorization and state check in the plugin's product retrieval path. The code trusts that WordPress core will filter unpublished content, but the plugin queries the product object directly and bypasses the visibility layer that front-end templates rely on.
Attack Vector
Exploitation requires only network access to the WordPress site. An attacker issues HTTP requests to the vulnerable plugin endpoint with sequential or enumerated product IDs. The server returns JSON containing product details for any matching record, including drafts and private items. No credentials, cookies, or user interaction are required. See the WPScan Vulnerability Report for technical details.
Detection Methods for CVE-2026-88929
Indicators of Compromise
- Repeated unauthenticated HTTP requests to the plugin's AJAX or REST endpoint with incrementing product ID parameters
- Response payloads containing product titles or prices that match records in wp_posts with a post_status of draft, pending, or private
- Elevated request volume from a single IP or user agent targeting WooCommerce product endpoints
Detection Strategies
- Review WordPress access logs for high-frequency requests to the plugin's action handler correlated with sequential product ID values
- Compare returned product identifiers in web server logs against the WooCommerce database to identify responses referencing unpublished products
- Deploy web application firewall rules that flag anonymous access to product detail endpoints outside the expected front-end flow
Monitoring Recommendations
- Enable verbose logging on the plugin's endpoint and forward logs to a centralized analytics platform for baseline analysis
- Alert on anonymous traffic spikes to admin-ajax.php or plugin-specific REST routes referencing product IDs
- Track outbound response sizes for the affected endpoint to identify bulk data extraction patterns
How to Mitigate CVE-2026-88929
Immediate Actions Required
- Upgrade the Product Badge, Label, Countdown Timer for WooCommerce plugin to version 7.5.2 or later on all WordPress installations
- Audit WooCommerce products in draft, pending, or private status for sensitive content that may have been exposed prior to patching
- Review web server access logs for signs of prior enumeration against the vulnerable endpoint
Patch Information
The vendor addressed the issue in version 7.5.2 by adding a publication status check before returning product data. Administrators should update through the WordPress plugin manager or by replacing the plugin files with the current release. Refer to the WPScan Vulnerability Report for advisory details.
Workarounds
- Deactivate the plugin until it can be updated to version 7.5.2 or later
- Restrict access to the plugin's endpoint using web application firewall rules that require authenticated sessions
- Temporarily move sensitive unpublished products out of the WooCommerce catalog until patching is complete
# Update the affected plugin using WP-CLI
wp plugin update product-badge-label-countdown-timer-for-woocommerce --version=7.5.2
