CVE-2026-12753 in Advance Product Search Plugin
Summary
by MITRE • 07/16/2026
The Advance Product Search- Voice & Ajax Search for WooCommerce plugin for WordPress is vulnerable to generic SQL Injection via the 's' and 'match' parameter in all versions up to, and including, 1.4.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The vulnerability identified in the Advance Product Search plugin for WooCommerce represents a critical security flaw that undermines the integrity of WordPress-based e-commerce platforms. This generic SQL injection vulnerability affects all versions up to and including 144, exposing systems to unauthorized data access and potential system compromise. The flaw stems from inadequate input validation and sanitization practices within the plugin's core functionality, specifically targeting the 's' and 'match' parameters that are processed without proper escaping mechanisms.
The technical implementation of this vulnerability occurs when user-supplied input is directly incorporated into SQL queries without appropriate preparation or parameterization. Attackers can exploit this weakness by crafting malicious input strings that manipulate the existing database queries to execute unintended operations. The lack of sufficient query preparation means that standard SQL injection prevention measures fail to protect against this particular attack vector, allowing attackers to inject additional SQL commands that can be executed within the context of the database connection.
Operationally, this vulnerability creates significant risks for e-commerce platforms utilizing the affected plugin, as unauthenticated attackers can potentially extract sensitive information from the underlying database. The impact extends beyond simple data theft to include potential system compromise, data manipulation, and unauthorized access to customer information. Attackers could leverage this vulnerability to retrieve user credentials, product catalogs, order histories, and other confidential business data that may be stored within the WordPress database structure.
The vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws in software applications, and represents a classic example of insufficient input validation and sanitization practices. From an adversarial perspective, this weakness maps to ATT&CK technique T1071.004 for application layer protocol manipulation and T1566 for credential access through exploitation of software vulnerabilities. Organizations operating affected systems face increased risk of data breaches and regulatory compliance violations that could result in substantial financial and reputational damage.
Mitigation strategies should prioritize immediate plugin updates to versions that address the SQL injection vulnerability, though organizations must verify that update procedures do not introduce compatibility issues with existing site functionality. Additional protective measures include implementing web application firewalls with SQL injection detection capabilities, applying proper input validation at multiple layers of the application architecture, and conducting regular security assessments of third-party plugins. Database access controls should be reviewed to ensure least privilege principles are enforced, and monitoring systems should be enhanced to detect anomalous database query patterns that may indicate exploitation attempts.
