The code does not create the file with explicit restrictive permissions, so its confidentiality depends on the process umask and pre-existing file permissions. More critically, `set_api_key()` only rejects empty values. Calling `strip()` removes leading and trailing whitespace but does not reject embedded carriage-return or newline characters. Consequently, an attacker-controlled key can append additional dotenv assignments. This is security-sensitive because `Settings` loads variables with the `XBY_GAOKAO_` prefix from `.env`. An injected assignment such as `XBY_GAOKAO_BASE_URL` can therefore ...[truncated 1835 chars]- Remediation
