CVE-2026-42727: WooCommerce Products Tables SQL Injection

CVE-2026-42727 Overview

CVE-2026-42727 is a blind SQL injection vulnerability in the RealMag777 Active Products Tables for WooCommerce plugin (profit-products-tables-for-woocommerce). The flaw affects all plugin versions up to and including 1.0.8. Unauthenticated attackers can inject crafted SQL fragments into plugin parameters that are concatenated into database queries without proper neutralization. Because WooCommerce stores order data, customer records, and authentication material in the WordPress database, successful exploitation exposes sensitive commercial data. The issue is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Unauthenticated remote attackers can extract WordPress and WooCommerce database contents through blind SQL injection, with a scope change permitting impact beyond the vulnerable component.

Affected Products

• RealMag777 Active Products Tables for WooCommerce — all versions through 1.0.8
• WordPress sites running WooCommerce with the profit-products-tables-for-woocommerce plugin installed
• E-commerce environments exposing the plugin's request handlers to anonymous traffic

Technical Details for CVE-2026-42727

Vulnerability Analysis

The vulnerability resides in request handling logic within the Active Products Tables for WooCommerce plugin. User-supplied input flows into a SQL statement without parameterization or escaping. An attacker manipulates the affected parameter to alter query structure, causing the database to evaluate attacker-controlled expressions. Because the application does not return query results directly, exploitation takes the form of blind SQL injection. Attackers infer data byte-by-byte using boolean conditions or time-based payloads such as SLEEP() and BENCHMARK(). The network attack vector requires no authentication or user interaction, and the scope change indicates that an attacker can reach data managed outside the immediate plugin context.

Root Cause

The root cause is improper neutralization of special elements used in an SQL command [CWE-89]. The plugin concatenates request parameters into SQL queries rather than using WordPress prepared statements through $wpdb->prepare(). Single quotes, comment markers, and SQL keywords pass through unfiltered into the query string.

Attack Vector

Exploitation occurs over HTTP or HTTPS against the WordPress front-end or AJAX endpoint exposed by the plugin. The attacker submits a crafted request containing SQL metacharacters in a parameter consumed by the vulnerable handler. Successful payloads enable enumeration of database schema, extraction of wp_users password hashes, and disclosure of WooCommerce customer and order tables. Refer to the Patchstack advisory for technical specifics.

No public proof-of-concept exploit is currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-42727

Indicators of Compromise

• HTTP requests containing SQL syntax such as UNION SELECT, SLEEP(, BENCHMARK(, AND 1=1, or encoded variants targeting plugin endpoints under /wp-content/plugins/profit-products-tables-for-woocommerce/
• Unusual admin-ajax.php traffic referencing plugin actions with quoted or comment-laden parameter values
• Anomalous response latency patterns consistent with time-based blind SQL injection probing
• Unexpected reads of wp_users, wp_usermeta, or WooCommerce order tables logged by database audit tooling

Detection Strategies

• Deploy a web application firewall ruleset that inspects parameters submitted to the plugin's endpoints for SQL injection signatures
• Enable MySQL or MariaDB general query logging temporarily to capture query patterns originating from the plugin during incident triage
• Correlate spikes in 500-series HTTP responses or extended request durations against requests targeting the plugin

Monitoring Recommendations

• Alert on outbound data transfers from the WordPress host that exceed historical baselines following requests to plugin endpoints
• Monitor authentication logs for password-spray or credential-stuffing activity against accounts whose hashes may have been extracted
• Track WordPress plugin inventory and version state across managed sites to identify hosts still running profit-products-tables-for-woocommerce1.0.8 or earlier

How to Mitigate CVE-2026-42727

Immediate Actions Required

• Disable or uninstall the Active Products Tables for WooCommerce plugin until a fixed release is verified and applied
• Restrict access to the affected WordPress site at the network edge while remediation is in progress
• Rotate WordPress administrator credentials, API keys, and WooCommerce payment gateway secrets if exploitation is suspected
• Audit the wp_users table and recent administrative actions for unauthorized account creation or privilege changes

Patch Information

At the time of publication, no fixed version is listed in the NVD record. The advisory indicates the issue affects versions through 1.0.8. Site operators should monitor the Patchstack advisory and the plugin's WordPress.org listing for a patched release.

Workarounds

• Remove the plugin directory profit-products-tables-for-woocommerce from wp-content/plugins/ if the product table functionality is not business-critical
• Place a WAF rule in front of WordPress that blocks SQL metacharacters in parameters consumed by the plugin's AJAX actions
• Apply database-level least privilege so the WordPress database user cannot read tables outside its required scope
• Enforce IP allowlisting on /wp-admin/ and admin-ajax.php where the plugin endpoints are reachable

# Example: temporarily disable the plugin via WP-CLI
wp plugin deactivate profit-products-tables-for-woocommerce
wp plugin delete profit-products-tables-for-woocommerce

# Example: Nginx rule to block obvious SQLi patterns against plugin endpoints
# location ~* /wp-content/plugins/profit-products-tables-for-woocommerce/ {
#     if ($args ~* "(union.*select|sleep\(|benchmark\(|information_schema)") {
#         return 403;
#     }
# }
