Summary
CVE-2026-66436 is an unauthenticated SQL Injection vulnerability affecting the "Active Products Tables for WooCommerce" WordPress plugin (also distributed as "profit-products-tables-for-woocommerce") developed by RealMag777. The flaw stems from improper neutralization of special elements in an SQL command (CWE-89) and allows remote, unauthenticated attackers to inject malicious SQL via a blind SQL injection technique. It carries a Critical CVSS v3.1 base score of 9.3, reflecting its network-exploitable, low-complexity, no-privilege-required nature.
Technical details
- Root cause: The plugin fails to sufficiently sanitize/escape user-supplied input before incorporating it into SQL queries executed against the WordPress/WooCommerce database, and does not use properly prepared statements for the affected query path.
- Trigger conditions: An attacker can exploit the vulnerability by sending crafted, unauthenticated HTTP requests to a site running the vulnerable plugin — no login, account, or user interaction is required.
- Attack vector: Network (remote), Attack Complexity: Low, Privileges Required: None, User Interaction: None (per CVSS vector).
- Impact: Classified as Blind SQL Injection (CAPEC-7); attackers can query and extract sensitive data from the site’s database (e.g., customer/order data, credentials, WooCommerce store information) and potentially degrade database/application availability. The vulnerability is scoped as "Changed" (S:C) with high confidentiality impact and low availability impact per the CVSS vector.
Affected software
- Plugin: Active Products Tables for WooCommerce (Professional products tables for WooCommerce store) — vendor RealMag777
- Affected versions: All versions up to and including 1.1.1
- Fixed version: 2.1.2 and later
Severity
- CVSS v3.1 Base Score: 9.3 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L
Mitigation and recommended actions
- Immediate: Update the "Active Products Tables for WooCommerce" plugin to version 2.1.2 or later, where the SQL injection has been remediated.
- If immediate patching is not possible:
- Temporarily deactivate the plugin on any public-facing WordPress/WooCommerce site until the update can be applied.
- Deploy or tune a Web Application Firewall (WAF) rule set to detect and block SQL injection payloads targeting plugin-specific endpoints/parameters.
- Monitor web server and database logs for anomalous query patterns or repeated probing consistent with blind SQL injection attempts.
- Restrict direct database access and ensure least-privilege database accounts are used by the WordPress installation to limit potential data exposure if exploited.
