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

Edit /admin/userLevel_deal.php to include CSRF token generation and validation
Restrict Admin Access
allLimit admin panel access to trusted IP addresses only
Add IP restrictions in .htaccess or web server configuration for /admin/ directory
🧯 If You Can't Patch
- Implement SameSite cookies and require re-authentication for sensitive actions
- Use browser extensions that block CSRF attacks and educate administrators about phishing risks
