CVE-2026-22242 Overview
CoreShop is a Pimcore-enhanced eCommerce solution used to build online storefronts. CVE-2026-22242 is a blind SQL injection vulnerability affecting all versions prior to 4.1.8. An authenticated administrator-level user can extract database contents using boolean-based or time-based injection techniques. The application connects to its database through a read-only, non-DBA account, which limits impact to confidential data disclosure. The vulnerability does not permit data modification or service disruption. Maintainers patched the issue in version 4.1.8.
Critical Impact
Authenticated administrators can exfiltrate arbitrary database contents through blind SQL injection, exposing customer records, order data, and other sensitive eCommerce information.
Affected Products
- CoreShop versions prior to 4.1.8
- Pimcore deployments integrating vulnerable CoreShop releases
- eCommerce environments built on the CoreShop framework

Technical Details for CVE-2026-22242
Vulnerability Analysis
The vulnerability is a blind SQL injection flaw classified under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command) and [CWE-564] (SQL Injection: Hibernate). User-controlled input reaches a SQL query without proper parameterization or sanitization. The application does not return query results directly to the attacker, requiring inference-based extraction.
An attacker uses boolean-based techniques to determine truth values by observing application response differences. Time-based techniques rely on SQL functions such as SLEEP() or BENCHMARK() to infer data byte by byte through measured response delays. Both techniques allow systematic extraction of database contents.
Exploitation requires high privileges, since only authenticated administrator-level accounts can reach the vulnerable endpoint. The database account configured for CoreShop is read-only and lacks database administrator rights, scoping impact to confidentiality of stored data.
Root Cause
The root cause is the construction of SQL statements using concatenated or unsanitized input within an administrative code path. Affected code paths were corrected in commit 59e84fec59d113952b6d28a9b30c6317f9e6e5dd, which introduced parameterized handling for the affected query logic. Review the GitHub Commit Update for the specific changes.
Attack Vector
The attack vector is network-based against the CoreShop administrative interface. An attacker must first obtain administrator credentials through credential theft, phishing, or insider access. With valid administrator authentication, the attacker submits crafted input to the vulnerable parameter and observes either response content variations (boolean-based) or response timing (time-based) to extract database rows one bit at a time.
No verified exploit code is publicly available. Refer to the GitHub Security Advisory GHSA-ch7p-mpv4-4vg4 for advisory details.
Detection Methods for CVE-2026-22242
Indicators of Compromise
- Administrator session activity producing unusually high query volumes against CoreShop database tables
- Web server logs containing SQL keywords such as SLEEP, BENCHMARK, AND 1=1, OR 1=2, or UNION SELECT within authenticated administrative requests
- Repeated requests to the same administrative endpoint with single-character parameter variations indicative of byte-by-byte extraction
- Database response times that spike consistently in tandem with administrative HTTP requests
Detection Strategies
- Inspect application and reverse proxy logs for SQL metacharacters and time-delay function names in parameters submitted by administrator sessions
- Correlate authenticated administrator request patterns with database query latency anomalies to identify time-based injection attempts
- Deploy web application firewall rules tuned for blind SQL injection signatures targeting the CoreShop admin path
Monitoring Recommendations
- Enable verbose query logging on the CoreShop database account and alert on queries containing conditional time-delay functions
- Monitor administrator account activity for high-volume sequential requests to the same endpoint within short time windows
- Track failed and successful administrator logins to detect credential compromise that would enable exploitation
How to Mitigate CVE-2026-22242
Immediate Actions Required
- Upgrade CoreShop to version 4.1.8 or later, which contains the patched query logic
- Rotate administrator credentials and enforce multi-factor authentication on all CoreShop admin accounts
- Audit administrator session logs for suspicious activity preceding the patch deployment
- Confirm the CoreShop database account remains read-only and non-DBA, limiting blast radius
Patch Information
Maintainers released the fix in CoreShop 4.1.8 via commit 59e84fec59d113952b6d28a9b30c6317f9e6e5dd. Apply this release through your standard Composer dependency update workflow. Reference the GitHub Security Advisory GHSA-ch7p-mpv4-4vg4 for upgrade guidance.
Workarounds
- Restrict network access to the CoreShop administrative interface using IP allowlists or a VPN
- Place a web application firewall in front of the admin interface with rules blocking SQL injection payloads and time-delay functions
- Reduce the number of administrator accounts and apply the principle of least privilege to limit exposure until patching
