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 flaw exists in all versions up to and including 1.3.1 and is due to improper neutralization of special elements in the 'groupKey' parameter. Specifically, the plugin fails to sufficiently escape or prepare the SQL query that incorporates this user-supplied parameter, allowing an attacker with Administrator-level access to append arbitrary SQL commands. This vulnerability is classified under CWE-89, which covers improper neutralization of special elements used in SQL commands. The attack vector is network-based with low attack complexity, but requires high privileges (administrator or above) and no user interaction. Exploiting this vulnerability can lead to unauthorized disclosure of sensitive information from the backend database, compromising confidentiality. However, it does not impact data integrity or availability. The CVSS v3.1 base score is 4.9 (medium severity), reflecting the moderate risk due to the privilege requirement and limited scope of impact. No public exploit code or active exploitation has been reported yet. The vulnerability was reserved on November 20, 2025, and published on December 3, 2025. The lack of patches currently necessitates immediate mitigation efforts by affected organizations.

The primary impact of CVE-2025-13495 is the unauthorized disclosure of sensitive data stored in the backend database of websites using the FluentCart plugin. Since the vulnerability allows SQL Injection via a parameter accessible only to authenticated administrators, attackers who have already compromised admin credentials can escalate their access by extracting confidential information such as user data, payment details, or business intelligence. This can lead to data breaches, regulatory non-compliance, reputational damage, and potential financial losses. Although the vulnerability does not directly affect data integrity or availability, the exposure of sensitive information can facilitate further attacks, including phishing or identity theft. Organizations relying on FluentCart for eCommerce operations globally are at risk, especially those with weak administrative access controls or insufficient monitoring. The medium CVSS score reflects that while exploitation requires privileged access, the consequences of data leakage are significant. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, as attackers may develop exploits once the vulnerability details become widely known.

1. Apply patches or updates from the vendor as soon as they become available to fix the SQL Injection vulnerability. 2. Until patches are released, restrict administrative access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA). 3. Implement Web Application Firewalls (WAFs) with custom rules to detect and block suspicious SQL syntax in the 'groupKey' parameter or other admin interface inputs. 4. Conduct regular audits of administrator accounts and monitor logs for unusual query patterns or access attempts. 5. Employ the principle of least privilege by limiting the number of users with administrator-level access. 6. Use database activity monitoring tools to detect anomalous queries that may indicate exploitation attempts. 7. Educate administrators about the risks of SQL Injection and encourage prompt reporting of suspicious behavior. 8. Consider isolating the WordPress environment and database to minimize lateral movement if compromise occurs. 9. Backup databases regularly and verify backups to ensure recovery capability in case of data compromise. 10. Engage in threat intelligence sharing to stay informed about emerging exploits targeting FluentCart.
