Prior to 0.4.80, the /api/settings/database endpoint allows full database export (containing all credentials, API keys, OAuth tokens, and settings) and full database import (complete overwrite) without any authentication requirement beyond the ALWAYS_PROTECTED middleware check, which only validates JWT or CLI token.
