CVE-2025-2203 is a medium-severity SQL Injection vulnerability (CWE-89) found in the FunnelKit WordPress plugin versions prior to 3.10.2. The vulnerability arises because the plugin fails to properly sanitize and escape a parameter before incorporating it into an SQL query. This improper handling allows an authenticated administrator user to inject malicious SQL code into the database query. The vulnerability requires no privileges beyond admin access and involves user interaction (admin performing an action that triggers the injection). The CVSS 3.1 base score is 6.1, reflecting network attack vector, low attack complexity, no privileges required beyond admin, and user interaction required. The vulnerability impacts confidentiality and integrity by allowing an attacker to read or modify data within the database, but does not affect availability. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. Although no known exploits are currently in the wild, the presence of this vulnerability in a popular WordPress plugin used for funnel and marketing automation poses a risk if exploited. Since FunnelKit is a plugin used primarily by WordPress sites for marketing funnels, the vulnerability could be leveraged to extract sensitive customer data or manipulate sales and marketing data stored in the database. The lack of a patch link suggests that a fix may be pending or not yet publicly available at the time of publication.

For European organizations, this vulnerability could lead to unauthorized disclosure or modification of sensitive customer and business data stored within WordPress databases. Given the GDPR and other data protection regulations in Europe, any data breach resulting from exploitation could lead to significant regulatory penalties and reputational damage. Organizations using FunnelKit for marketing automation or sales funnels may have customer profiles, transaction records, or campaign data at risk. Attackers exploiting this vulnerability could manipulate marketing data, leading to financial losses or misleading business decisions. The requirement for admin-level access limits the risk to some extent, but insider threats or compromised admin accounts could be leveraged to exploit this flaw. Additionally, the vulnerability could be chained with other exploits to escalate privileges or pivot within the network. The impact on data confidentiality and integrity is significant, especially for organizations handling personal data or sensitive commercial information.

European organizations should immediately verify the version of FunnelKit installed on their WordPress sites and upgrade to version 3.10.2 or later once available. Until a patch is released, organizations should restrict admin access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA) for all admin accounts. Regularly audit admin activities and monitor logs for suspicious SQL queries or unusual database activity. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting FunnelKit parameters. Additionally, implement database-level protections such as least privilege access for WordPress database users to limit the impact of any injection attempts. Conduct thorough security assessments and penetration tests focusing on WordPress plugins to identify similar injection flaws. Finally, maintain an incident response plan tailored to WordPress environments to quickly respond to any exploitation attempts.
