CVE-2026-22242
📋 TL;DR
CoreShop versions before 4.1.8 contain a blind SQL injection vulnerability that allows authenticated administrator users to extract database contents using boolean-based or time-based techniques. The vulnerability only affects authenticated administrators and the database account is read-only, limiting impact to data disclosure without modification or service disruption.

⚠️ Risk & Real-World Impact
Worst Case
Confidential database contents could be fully extracted by a malicious administrator, potentially exposing sensitive customer data, order information, or business data.
Likely Case
Limited data extraction by a compromised administrator account, exposing some confidential information but not causing system disruption.
If Mitigated
No impact if proper access controls prevent unauthorized administrator access and the system is patched.
🎯 Exploit Status
Exploitation requires administrator credentials and knowledge of blind SQL injection techniques
🛠️ Fix & Mitigation

Restrict Administrator Access
allLimit administrator account access to trusted personnel only and implement strong authentication controls
Database Query Monitoring
allImplement database query logging and monitoring to detect suspicious SQL injection attempts
🧯 If You Can't Patch
- Implement strict access controls for administrator accounts and monitor for suspicious activity
- Deploy a web application firewall (WAF) with SQL injection protection rules
🔍 How to Verify
Check if Vulnerable:
Check CoreShop version via composer: 'composer show coreshop/core-shop | grep versions'Check Version:
composer show coreshop/core-shop | grep versionsVerify Fix Applied:
Verify version is 4.1.8 or higher: 'composer show coreshop/core-shop | grep versions'📡 Detection & Monitoring
Log Indicators:
- Unusual database query patterns from administrator accounts
- Multiple failed boolean-based SQL queries
- Time-delayed database responses
Network Indicators:
- Repeated SQL-like parameter manipulation in POST/GET requests from authenticated sessions
