SECRETS_PATH_DOTENV

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    index.js, line 12 const ENV_FILE = path.join(ZEN_DIR, '.env');

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.
