Yes, you can validate file extensions and content-types for Litestar API endpoints by applying explicit per-field validation rules. Typed UploadFile inputs enforce these specific content-type and extension policies to guard server resources.

Litestar secure file upload handling provides malware scanning integration guidance. This feature sits alongside memory-safe streaming and validation rules to ensure uploaded files are checked before storage pipeline processing.

You should not use typed UploadFile inputs for static asset serving or general file-response behavior. This secure multipart upload handling is designed exclusively for API endpoints receiving single or multiple files in request bodies.
