CVE-2025-13495 is an SQL Injection vulnerability identified in the FluentCart plugin for WordPress, a popular eCommerce solution designed to be fast and lightweight. The vulnerability exists due to improper neutralization of special characters in the 'groupKey' parameter, which is used in SQL queries without adequate escaping or parameterization. This flaw allows an attacker with authenticated Administrator-level access to append arbitrary SQL commands to existing queries. Consequently, attackers can extract sensitive information from the underlying database, such as customer data, order details, or configuration settings. The vulnerability affects all versions up to and including 1.3.1. The CVSS v3.1 base score is 4.9 (medium), reflecting the network attack vector with low complexity but requiring high privileges and no user interaction. The impact is primarily on confidentiality, with no direct effect on integrity or availability. No public exploits have been reported yet, and no official patches were linked at the time of disclosure. The vulnerability stems from CWE-89, indicating a failure to properly sanitize or parameterize SQL inputs, a common and critical web application security issue. Given the plugin’s role in eCommerce, exploitation could lead to significant data breaches if attackers gain Administrator credentials.

For European organizations, especially those operating eCommerce platforms using WordPress and FluentCart, this vulnerability poses a risk of sensitive data exposure, including customer personal information and transactional data. Such data breaches can lead to regulatory penalties under GDPR, reputational damage, and loss of customer trust. Since exploitation requires Administrator-level access, the threat is somewhat mitigated by internal access controls; however, compromised administrator accounts or insider threats could enable exploitation. The vulnerability does not affect system availability or data integrity directly, so service disruption or data manipulation risks are low. Nonetheless, the confidentiality impact is significant, particularly for organizations handling large volumes of personal and payment data. The lack of known exploits reduces immediate risk but should not lead to complacency. European eCommerce businesses are often targets for data theft due to the value of their customer data, making timely mitigation critical.

1. Monitor the vendor’s official channels for a security patch and apply it promptly once available. 2. Until a patch is released, restrict Administrator access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of credential compromise. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'groupKey' parameter. 4. Conduct regular security audits and code reviews of customizations or integrations involving FluentCart to identify potential injection points. 5. Employ database activity monitoring to detect unusual query patterns that may indicate exploitation attempts. 6. Limit the exposure of the WordPress admin interface by IP whitelisting or VPN access where feasible. 7. Educate administrators on phishing and social engineering risks to prevent credential theft. 8. Backup databases regularly and ensure backups are securely stored to support recovery if needed.
