CVE-2025-14314 identifies a Blind SQL Injection vulnerability in Roxnor's PopupKit plugin, a tool used to create popup elements on websites. The vulnerability arises from improper neutralization of special characters within SQL commands, allowing attackers to inject arbitrary SQL code. Blind SQL Injection means attackers cannot see the direct output of their queries but can infer data by observing application behavior or response times. The affected versions include all releases up to and including 2.1.5. Exploitation requires no authentication or user interaction, making it accessible to remote attackers. The vulnerability could enable unauthorized access to backend databases, leading to data leakage, unauthorized data modification, or denial of service. No patches or exploit code are currently publicly available, but the risk remains significant due to the nature of SQL injection flaws. The vulnerability was reserved and published in December 2025 by Patchstack, but no CVSS score has been assigned yet. The lack of a CVSS score necessitates an independent severity assessment based on impact and exploitability factors.

For European organizations, this vulnerability could lead to severe consequences including unauthorized disclosure of sensitive customer or business data, data integrity compromise, and potential disruption of web services. Organizations relying on PopupKit for customer engagement or marketing may face reputational damage and regulatory penalties under GDPR if personal data is exposed. The blind nature of the SQL injection complicates detection but does not reduce the potential for data exfiltration or backend manipulation. Attackers could leverage this vulnerability to pivot into deeper network layers or deploy further attacks. The absence of known exploits currently provides a window for proactive mitigation, but the risk of future exploitation remains high. Industries such as e-commerce, finance, and healthcare in Europe, which often use WordPress plugins like PopupKit, are particularly vulnerable.

Immediate mitigation should focus on monitoring and restricting database query inputs related to PopupKit. Organizations should implement strict input validation and sanitization on all user-supplied data interacting with the plugin. Deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts can provide an effective interim defense. Administrators should track vendor communications for official patches or updates and apply them promptly once released. Conducting code reviews and penetration testing focused on SQL injection vectors in PopupKit is recommended. If patching is delayed, consider disabling or replacing the plugin with a secure alternative. Logging and alerting on anomalous database query patterns can help detect exploitation attempts early. Finally, ensure database accounts used by the plugin have the least privileges necessary to limit potential damage.
