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

Rescanned at commit a742b16f54df, 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/lib/fetch.ts, line 1 // Fetch with timeout - wraps fetch() with an AbortController that auto-cancels.

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 5 .env

  • SECRETS_ENV_READ Note

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

    src/services/auth/crypto.ts, line 20 const envSecret = process.env.FIBX_SESSION_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.
