CVE-2026-42761: WooCommerce Products Tables SQLi Flaw

CVE-2026-42761 Overview

CVE-2026-42761 is a blind SQL injection vulnerability in the RealMag777 Active Products Tables for WooCommerce plugin, tracked under the profit-products-tables-for-woocommerce slug. The flaw affects all plugin versions up to and including 1.0.9. Unauthenticated attackers can inject malicious SQL statements through unsanitized input that reaches database queries. Successful exploitation allows attackers to extract sensitive data from the WordPress database, including customer records, order information, and authentication material. The vulnerability is classified under CWE-89 and requires no user interaction.

Critical Impact

Unauthenticated network-based blind SQL injection enabling database content extraction from WooCommerce storefronts running the affected plugin.

Affected Products

• RealMag777 Active Products Tables for WooCommerce plugin
• Plugin slug: profit-products-tables-for-woocommerce
• All versions from initial release through 1.0.9

Technical Details for CVE-2026-42761

Vulnerability Analysis

The vulnerability stems from improper neutralization of special elements used in an SQL command within the Active Products Tables for WooCommerce plugin. User-supplied parameters reach SQL queries without parameterization or sufficient sanitization. Attackers exploit this through blind injection techniques, inferring database contents from application response differences or timing variations.

The issue is exploitable over the network without authentication or user interaction. Because the vulnerability has scope-changing properties, exploitation can affect resources beyond the vulnerable plugin component. The Patchstack advisory confirms the affected version range covers all releases up to and including 1.0.9.

Root Cause

The root cause is missing input validation and absence of prepared statements in plugin code that constructs database queries. WordPress provides the $wpdb->prepare() API for safe query parameterization, but the affected code paths concatenate untrusted input directly into SQL statements. This classic [CWE-89] pattern allows attacker-controlled data to alter query semantics.

Attack Vector

Attackers send crafted HTTP requests to plugin endpoints that process product table queries. Boolean-based and time-based blind SQL injection techniques let unauthenticated remote attackers infer query results without direct output. Repeated requests enable systematic extraction of database contents, including the wp_users table containing password hashes and the wp_options table containing site secrets.

The vulnerability is described in prose only, as no public proof-of-concept code has been released. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2026-42761

Indicators of Compromise

• HTTP requests to plugin endpoints containing SQL keywords such as UNION, SELECT, SLEEP, or BENCHMARK in query parameters
• Anomalous response latency patterns suggesting time-based blind injection probing
• Unusual database read activity from the WordPress web user account against wp_users or wp_options tables
• Web server access logs showing repeated parameter fuzzing against profit-products-tables-for-woocommerce URIs

Detection Strategies

• Deploy web application firewall rules that flag SQL meta-characters in requests targeting the plugin's AJAX and REST endpoints
• Enable MySQL general query logging temporarily on affected hosts to identify malformed or attacker-crafted SQL
• Correlate WordPress audit logs with reverse proxy logs to identify unauthenticated probing of plugin parameters

Monitoring Recommendations

• Alert on HTTP 500 responses originating from plugin endpoints, which often indicate injection error states
• Monitor for outbound DNS or HTTP callbacks from the web server that could indicate exfiltration
• Track sudden spikes in request volume against any URI path containing profit-products-tables-for-woocommerce

How to Mitigate CVE-2026-42761

Immediate Actions Required

• Identify all WordPress installations running the Active Products Tables for WooCommerce plugin and inventory versions
• Deactivate the plugin immediately on sites running version 1.0.9 or earlier until a patched release is available
• Restrict access to WordPress admin and plugin endpoints via IP allowlisting where feasible
• Rotate WordPress administrator passwords, API keys, and salts stored in wp-config.php if compromise is suspected

Patch Information

At the time of publication, no fixed version is listed in the available CVE data. Monitor the Patchstack Vulnerability Report and the WordPress plugin repository for an updated release above 1.0.9. Apply the vendor patch as soon as it becomes available.

Workarounds

• Disable and remove the plugin until a vendor patch is released and validated
• Deploy WAF signatures to block SQL injection payloads targeting WooCommerce product table endpoints
• Apply virtual patching at the reverse proxy layer to reject requests containing SQL control characters in plugin parameters
• Enforce least-privilege on the WordPress database user to limit data accessible during successful exploitation

# Example: deactivate the vulnerable plugin via WP-CLI
wp plugin deactivate profit-products-tables-for-woocommerce
wp plugin status profit-products-tables-for-woocommerce
