CVE-2026-22850

Koko Analytics is an open-source analytics plugin for WordPress. Versions prior to 2.1.3 are vulnerable to arbitrary SQL execution through unescaped analytics export/import and permissive admin SQL import. Unauthenticated visitors can submit arbitrary path (pa) and referrer (r) values to the public tracking endpoint in src/Resources/functions/collect.php, which stores those strings verbatim in the analytics tables. The admin export logic in src/Admin/DataExport.php writes these stored values directly into SQL INSERT statements without escaping. A crafted path such as "),('999','x');DROP TABLE wpusers;-- breaks out of the value list. When an administrator later imports that export file, the import handler in src/Admin/DataImport.php reads the uploaded SQL with filegetcontents, performs only a superficial header check, splits on semicolons, and executes each statement via $wpdb->query with no validation of table names or statement types. Additionally, any authenticated user with managekokoanalytics can upload an arbitrary .sql file and have it executed in the same permissive way. Combined, attacker-controlled input flows from the tracking endpoint into exported SQL and through the import execution sink, or directly via malicious uploads, enabling arbitrary SQL execution. In a worst-case scenario, attackers can achieve arbitrary SQL execution on the WordPress database, allowing deletion of core tables (e.g., wpusers), insertion of backdoor administrator accounts, or other destructive/privilege-escalating actions. Version 2.1.3 patches the issue.
