CVE-2025-26875 identifies a critical SQL Injection vulnerability in the Multiple Shipping And Billing Address For Woocommerce plugin developed by silverplugins217. This plugin enables WooCommerce users to manage multiple shipping and billing addresses, enhancing e-commerce functionality. The vulnerability arises from improper neutralization of special characters in SQL commands, allowing attackers to inject arbitrary SQL code. This can lead to unauthorized database queries, potentially exposing sensitive customer data, altering order information, or corrupting the database. The affected versions include all releases up to and including version 1.3. The flaw is particularly dangerous because it may be exploited without requiring user authentication or interaction, making it accessible to remote attackers. Although no public exploits have been reported yet, the lack of a patch increases the risk of future exploitation. The vulnerability impacts the core data integrity and confidentiality of WooCommerce stores using this plugin, which are often critical for business operations. The absence of a CVSS score necessitates a severity assessment based on the nature of the vulnerability and its potential impact. Given the widespread use of WooCommerce globally, this vulnerability poses a significant threat to e-commerce platforms relying on this plugin for address management.

The SQL Injection vulnerability in this WooCommerce plugin can have severe consequences for affected organizations. Attackers could gain unauthorized access to sensitive customer data, including personal and payment information, leading to data breaches and privacy violations. They might also manipulate order details, causing financial losses or operational disruptions. The integrity of the e-commerce database could be compromised, resulting in corrupted data or denial of service if critical tables are damaged. This undermines customer trust and can lead to regulatory penalties under data protection laws such as GDPR or CCPA. The ease of exploitation without authentication broadens the attack surface, increasing the likelihood of automated or targeted attacks. Organizations worldwide using this plugin risk significant reputational damage and financial impact if the vulnerability is exploited. The threat is particularly acute for businesses with high transaction volumes or those in regulated industries where data integrity and confidentiality are paramount.

To mitigate this vulnerability, organizations should immediately audit their WooCommerce installations to identify the use of the Multiple Shipping And Billing Address For Woocommerce plugin and its version. Until an official patch is released, apply strict input validation and sanitization on all user-supplied data related to shipping and billing addresses. Implement Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting this plugin's endpoints. Limit database user permissions to the minimum necessary to reduce potential damage from injection attacks. Monitor logs for unusual database queries or access patterns indicative of exploitation attempts. Consider temporarily disabling the plugin if it is not critical to business operations. Stay informed through vendor and security advisories for patch releases and apply updates promptly. Additionally, conduct regular security assessments and penetration testing focused on SQL Injection vulnerabilities in e-commerce environments.
