🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No

Parameterized Queries
allRewrite database queries to use parameterized statements instead of string concatenation.
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns
- Restrict database user permissions to minimum required access
🔍 How to Verify
Check if Vulnerable:
Test the 'user_firstname' parameter with SQL injection payloads like ' OR '1'='1
Check Version:
Check CMS configuration files or admin panel for version information
Verify Fix Applied:
Verify that SQL injection payloads no longer execute and return error messages
