Implement server-side validation to reject paths containing '../', '..\', or absolute paths
Web Server Restrictions
allConfigure web server to restrict access to sensitive directories
Configure .htaccess (Apache) or nginx location blocks to limit file access
🧯 If You Can't Patch
- Implement a web application firewall (WAF) with directory traversal protection rules
- Restrict network access to the application using firewall rules or network segmentation
