CVE-2026-23959 in CoreShop
Summary
by MITRE • 01/22/2026
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.

The vulnerability CVE-2026-23959 represents a critical error-based sql injection flaw discovered in CoreShop's admin panel functionality. This issue specifically affects the CustomerTransformerController component within the CoreShop platform, which is designed as a pimcore enhanced ecommerce solution. The vulnerability exists in versions prior to 4.1.9, indicating that the developers have acknowledged and addressed this security concern in their subsequent releases. The affected endpoint demonstrates a fundamental flaw in input validation and query construction practices, where user-supplied data is directly interpolated into sql queries without proper sanitization or parameterization mechanisms.
The technical implementation of this vulnerability stems from improper handling of user input within the CustomerTransformerController's database operations. When administrators or authorized users interact with the affected functionality, malicious input can be passed through the endpoint and directly embedded into sql statements. This creates a scenario where database error messages may be exposed to attackers, potentially revealing sensitive information about the database structure, table names, and column schemas. The error-based nature of the injection means that attackers can exploit this weakness to extract database contents through carefully crafted payloads that trigger specific error responses, allowing for information disclosure and potential data exfiltration.
The operational impact of this vulnerability extends beyond simple data exposure, as it compromises the integrity and confidentiality of the ecommerce platform's backend systems. Attackers who successfully exploit this vulnerability could gain unauthorized access to customer data, transaction records, and other sensitive business information stored within the CoreShop database. The vulnerability affects the admin panel specifically, which means that successful exploitation could provide attackers with elevated privileges and access to administrative functions. This creates a significant risk for organizations using CoreShop versions prior to 4.1.9, as the attack surface includes not only data extraction but also potential system compromise through further exploitation of database vulnerabilities. The vulnerability aligns with CWE-89 which specifically addresses sql injection flaws, and could potentially map to ATT&CK technique T1071.004 for application layer protocol manipulation.
Organizations utilizing CoreShop must prioritize immediate remediation through upgrading to version 4.1.9 or later, which includes the necessary fixes for this sql injection vulnerability. Security teams should conduct comprehensive assessments of their CoreShop installations to identify any instances running vulnerable versions and implement proper patch management procedures. Additional defensive measures should include monitoring database logs for suspicious activity, implementing web application firewalls to detect and block malicious sql injection attempts, and conducting regular security audits of admin panel endpoints. The vulnerability demonstrates the critical importance of proper input validation and parameterized queries in preventing sql injection attacks, particularly in administrative interfaces where elevated privileges may be available. Organizations should also consider implementing database activity monitoring solutions to detect anomalous query patterns that might indicate exploitation attempts, and establish incident response procedures to address potential data breaches resulting from such vulnerabilities.
