CVE-2025-13495 identifies a SQL Injection vulnerability in the FluentCart plugin for WordPress, a popular eCommerce solution designed to be fast, lightweight, and simple. The vulnerability exists in all versions up to and including 1.3.1 and is caused by insufficient escaping and improper preparation of the 'groupKey' parameter in SQL queries. Specifically, the plugin fails to properly neutralize special SQL elements in this user-supplied parameter, allowing an attacker with administrator-level privileges to append additional SQL commands to existing queries. This can lead to unauthorized extraction of sensitive information from the underlying database, such as customer data, order details, or configuration settings. The vulnerability requires no user interaction but does require high privileges, limiting exploitation to trusted users with admin access. The CVSS 3.1 base score is 4.9 (medium), reflecting the network attack vector, low attack complexity, and high privileges required, with a significant impact on confidentiality but no impact on integrity or availability. No public exploits or patches are currently available, but the vulnerability has been officially published and assigned by Wordfence. The flaw is categorized under CWE-89, which covers improper neutralization of special elements in SQL commands, a common and critical web application security issue. Given FluentCart’s role in eCommerce, exploitation could expose sensitive business and customer data, undermining trust and compliance with data protection regulations.

For European organizations, the impact of this vulnerability is primarily the potential unauthorized disclosure of sensitive customer and transactional data stored in the FluentCart database. This can lead to violations of GDPR and other privacy regulations, resulting in legal penalties and reputational damage. Since the vulnerability requires administrator-level access, the risk is heightened if internal accounts are compromised or malicious insiders exist. The exposure of sensitive data could also facilitate further attacks such as identity theft, fraud, or targeted phishing campaigns. Although the vulnerability does not affect data integrity or availability, the confidentiality breach alone is significant for eCommerce businesses handling personal and payment information. Organizations relying on FluentCart for their online stores may face operational disruptions if they need to take systems offline to remediate or investigate incidents. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability becomes widely known.

Immediate mitigation should focus on restricting administrator access to trusted personnel only and enforcing strong authentication mechanisms such as multi-factor authentication to reduce the risk of credential compromise. Organizations should monitor database query logs for unusual or unexpected SQL commands that could indicate exploitation attempts. Since no official patch is currently available, administrators can implement temporary mitigations by applying strict input validation and sanitization on the 'groupKey' parameter, ensuring it only accepts expected values and rejects any suspicious input. Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter can also reduce risk. Once the vendor releases a security update, prompt application of the patch is critical. Additionally, regular security audits and penetration testing focused on WordPress plugins can help identify similar vulnerabilities proactively. Backup procedures should be reviewed and tested to ensure data recovery in case of compromise.
