File Upload Restriction
allImplement strict file upload validation to only allow specific image file types and block PHP files
Modify upload handling code to check file extensions and MIME types
Implement server-side file type verification
Web Application Firewall Rules
allConfigure WAF to block PHP file uploads and suspicious upload patterns
Add WAF rule: deny requests with .php files in upload parameters
Block requests with PHP code patterns in file content
🧯 If You Can't Patch
- Disable the Select Image functionality completely
