CVE-2025-31534: Critical SQL Injection Vulnerability in Shopperdotcom Shopper

A critical SQL injection vulnerability (CVE-2025-31534) has been identified in the Shopperdotcom Shopper platform, affecting all versions up to 3.2.5. With a CVSS score of 9.3 (Critical), this vulnerability allows attackers to execute arbitrary SQL commands through improper neutralization of special elements in SQL queries¹.

Technical Overview

The vulnerability stems from insufficient input validation in the Shopperdotcom Shopper application, specifically in how user-supplied data is incorporated into SQL queries. According to the CVE description, the flaw enables attackers to manipulate database queries through crafted input parameters. This type of vulnerability, classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), is particularly dangerous as it can lead to unauthorized data access, modification, or deletion¹.

SQL injection vulnerabilities remain prevalent in web applications, as evidenced by recent similar findings. The CVE database shows multiple SQL injection vulnerabilities reported in early 2025, including CVE-2025-29635 (affecting patient-report.php) and CVE-2025-30569 (in WordPress WP Featured Entries plugin)². These cases demonstrate the persistent challenge of proper input sanitization across different platforms.

Impact and Affected Systems

The Shopperdotcom Shopper vulnerability affects all versions up to and including 3.2.5. While the exact attack vector isn’t specified in the public disclosure, typical SQL injection points in e-commerce platforms include search functions, product filters, and user authentication fields. The critical severity rating suggests the vulnerability could be exploited remotely without authentication, potentially compromising the entire database backend.

Successful exploitation could lead to:

Unauthorized access to customer data (including personal and payment information)
Modification of product listings and pricing
Complete database compromise leading to system takeover
Potential pivot point for further network exploitation

Detection and Mitigation

Organizations using Shopperdotcom Shopper should immediately check their version number and upgrade to any patched version released after 3.2.5. Temporary mitigation strategies include:

Action	Implementation
Input Validation	Implement strict whitelist validation for all user inputs
Parameterized Queries	Rewrite database queries using prepared statements
WAF Rules	Deploy SQL injection detection rules in web application firewalls
Database Monitoring	Monitor for unusual database query patterns

The CVE program, managed by MITRE and sponsored by CISA, provides standardized identifiers for such vulnerabilities, enabling organizations to track and respond to threats systematically². Security teams should monitor the official CVE database for updates on this vulnerability.

Conclusion

CVE-2025-31534 represents a significant threat to organizations using vulnerable versions of Shopperdotcom Shopper. The critical severity rating underscores the importance of prompt patching and thorough security reviews of all database interaction points in web applications. As SQL injection continues to be a common attack vector, developers should prioritize secure coding practices, particularly proper input validation and parameterized queries.

Security teams should incorporate this vulnerability into their threat models and ensure proper detection mechanisms are in place. The standardized CVE system remains an essential resource for tracking such vulnerabilities and coordinating response efforts across the security community.
