This medium-severity CVE scores 4.9 under NVD CVSS v3. EPSS exploit probability: 0.4%, top 69% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

CoreShop is a Pimcore enhanced eCommerce solution. An error-based SQL Injection vulnerability was identified in versions prior to 4.1.9 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. Version 4.1.9 fixes the issue.
