CVE-2026-22850 is an SQL injection vulnerability affecting Koko Analytics, an open-source WordPress analytics plugin. Versions before 2.1.3 fail to properly sanitize user input submitted to the public tracking endpoint (specifically the 'pa' and 'r' parameters), which are stored verbatim in the plugin's analytics database tables. When administrators export analytics data, these stored values are embedded directly into SQL INSERT statements without escaping, allowing crafted inputs to break out of the intended SQL context. Upon import, the plugin reads the uploaded SQL export file, performs only superficial header checks, splits the content on semicolons, and executes each statement via WordPress's $wpdb->query without validating the SQL commands or table names. This chain enables unauthenticated attackers to inject arbitrary SQL commands that execute with the privileges of the WordPress database user. Furthermore, any authenticated user with the 'manage_koko_analytics' capability can upload arbitrary .sql files, which are executed similarly without validation, increasing the attack surface. Potential impacts include deletion of core WordPress tables such as wp_users, creation of unauthorized administrator accounts, and other destructive or privilege-escalating actions. The vulnerability is rated high severity with a CVSS 3.1 score of 8.4, reflecting its network exploitability, high impact on confidentiality, integrity, and availability, and the requirement for user interaction but no authentication for the public tracking vector. The issue was patched in version 2.1.3 of Koko Analytics.

For European organizations, this vulnerability poses a significant risk to WordPress sites using Koko Analytics versions prior to 2.1.3. Exploitation can lead to full compromise of the WordPress database, including deletion of user accounts, insertion of backdoors, and potential site defacement or data theft. This can disrupt business operations, damage reputation, and lead to regulatory non-compliance, especially under GDPR where personal data breaches must be reported. The ability for unauthenticated attackers to inject SQL commands increases the risk of widespread exploitation. Additionally, insider threats or compromised accounts with manage_koko_analytics privileges can leverage the import functionality to execute arbitrary SQL. Given the popularity of WordPress in Europe for business and governmental websites, the impact can be broad, affecting sectors such as e-commerce, public administration, and media. Recovery may require database restoration and forensic analysis, incurring operational costs and downtime.

European organizations should immediately update Koko Analytics to version 2.1.3 or later to apply the official patch. Until patched, restrict access to the WordPress admin area and specifically limit the 'manage_koko_analytics' capability to trusted administrators only. Implement Web Application Firewall (WAF) rules to detect and block suspicious SQL injection payloads targeting the tracking endpoint parameters 'pa' and 'r'. Regularly audit and monitor analytics export/import activities for unusual files or commands. Employ database activity monitoring to detect unauthorized SQL execution. Backup WordPress databases frequently and verify backup integrity to enable recovery from destructive attacks. Educate administrators on the risks of importing untrusted SQL files. Consider disabling the analytics export/import functionality if not essential. Finally, conduct vulnerability scanning and penetration testing to identify any residual risks related to this plugin or similar components.
