CVE-2026-23959Public exploitNetwork attack vector

Authenticated data extraction via unparameterized name lookup

Published Jan 22, 2026 · Updated Jan 22, 2026

SQL injection in CoreShop before 4.1.9 allows remote authenticated users with admin-panel access to extract database data. CustomerTransformerController passes the user-controlled value parameter into a name LIKE condition through sprintf without escaping or parameter binding. Administrative authentication is required; successful error-based or blind queries disclose database errors, enumerate schema details, and extract data.
