CVE-2025-14169 identifies a critical SQL Injection vulnerability in the FunnelKit – Funnel Builder for WooCommerce Checkout plugin for WordPress, specifically in all versions up to and including 3.13.1.5. The vulnerability is due to improper neutralization of special elements used in SQL commands (CWE-89), where the 'opid' parameter is insufficiently escaped and incorporated into SQL queries without proper preparation or parameterization. This flaw allows unauthenticated attackers to inject arbitrary SQL code via the 'opid' parameter, enabling time-based blind SQL Injection attacks. Such attacks can be used to infer sensitive information from the backend database by measuring response delays, even without direct error messages or visible data leakage. The vulnerability is remotely exploitable over the network without any authentication or user interaction, increasing its risk profile. The CVSS v3.1 score of 7.5 reflects high severity, primarily due to the high impact on confidentiality, as attackers can extract sensitive data, while integrity and availability are not directly impacted. No patches or fixes have been linked yet, and no known exploits are reported in the wild, but the vulnerability's presence in a widely used WooCommerce plugin makes it a significant threat vector for e-commerce websites.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the FunnelKit plugin, this vulnerability could lead to unauthorized disclosure of sensitive customer data, including personal and payment information stored in the backend database. Such data breaches can result in regulatory penalties under GDPR, reputational damage, and financial losses. The ability for unauthenticated remote attackers to exploit this vulnerability increases the risk of widespread attacks. Additionally, attackers could leverage extracted data for further attacks such as identity theft, fraud, or targeted phishing campaigns. The lack of impact on data integrity and availability reduces the risk of service disruption but does not diminish the severity of confidentiality breaches. Organizations relying on this plugin without timely updates or mitigations are at heightened risk, particularly those with large customer bases or handling sensitive personal data.

European organizations should immediately audit their WordPress installations to identify the presence of the FunnelKit – Funnel Builder for WooCommerce Checkout plugin and verify its version. Until an official patch is released, it is critical to implement compensating controls such as web application firewalls (WAFs) configured to detect and block SQL Injection attempts targeting the 'opid' parameter. Input validation and sanitization should be enforced at the application level where possible. Restricting access to the affected plugin endpoints via IP whitelisting or VPNs can reduce exposure. Monitoring web server and application logs for suspicious query patterns or abnormal delays can help detect exploitation attempts. Organizations should subscribe to vendor advisories for updates and apply patches promptly once available. Additionally, conducting regular security assessments and penetration testing focused on SQL Injection vulnerabilities will help identify and remediate similar issues proactively.
