The server demonstrates strong security practices including comprehensive input validation (Pydantic schemas), robust URL/SSRF protection with explicit blocking of dangerous protocols and private IP ranges, and thorough SQL injection prevention via parameterized queries and psycopg2.sql. Dynamic SQL generation is handled safely. Temporary files and cleanup are managed. Potential minor risks include implicit Jinja2 auto-escaping (though usually safe by default) for metadata rendering in embed pages, and reliance on external binaries (FFmpeg, ExifTool) requiring trust in their security. Authentication uses a simple, configurable bearer token, which is noted as a limitation for production but adequate for MVP.
