CVE-2026-23959: CoreShop Vulnerable to SQL Injection via Admin customer-company-modifier

January 21, 2026 (updated January 22, 2026)

An error-based SQL Injection vulnerability was identified in the CustomerTransformerController within the CoreShop admin panel. The affected endpoint improperly interpolates user-supplied input into a SQL query, leading to database error disclosure and potential data extraction.

This issue is classified as MEDIUM severity, as it allows SQL execution in an authenticated admin context.
