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

Rescanned at commit eba9e5ff8d45, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED 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/client.ts, line 914 * omit Content-Type here so fetch() can set its own multipart boundary.

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/index.ts, line 504 `Use directly as DATABASE_URL (add .env to .gitignore):`,

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    src/index.ts, line 1147 tar = subprocess.check_output(["tar", "czf", "-", "-C", project_dir, "."])

  • SECRETS_ENV_READ Note

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

    src/client.ts, line 896 const tok = process.env["INSTANODE_TOKEN"];

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.
