APIExperts Square for WooCommerce SQLi (CVE-2026-45211) Exposes E-commerce Data
A critical SQL Injection vulnerability, tracked as CVE-2026-45211, has been identified in Saad Iqbal’s APIExperts Square for WooCommerce plugin. The National Vulnerability Database assigns this a CVSS v3.1 score of 8.5 (HIGH), indicating severe risk. This flaw, categorized as CWE-89, allows for Blind SQL Injection.
The vulnerability impacts APIExperts Square for WooCommerce versions up to and including 4.7.1. Attackers can exploit this to extract sensitive data from affected e-commerce databases without requiring complex authentication, leveraging specially crafted SQL commands. The ‘Improper Neutralization of Special Elements used in an SQL Command’ is a classic attack vector, and its presence in a widely used e-commerce plugin is concerning.
For defenders, this means a direct threat to customer data, order details, and potentially payment information if not properly segmented. The attacker’s calculus here is simple: high impact, relatively low effort. The widespread adoption of WooCommerce makes this a prime target for opportunistic attackers looking to exfiltrate data or disrupt operations.
