Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit cfe605569717, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    src/utils.ts, line 63 const response = await fetch(url, { headers });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/auth.ts, line 46 // Load environment variables from .env file located in the project root

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/auth.ts, line 54 secret: process.env.FITBIT_CLIENT_SECRET || '',

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
