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

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.

    index.ts, line 308 probe = new WebSocket(`ws://${hostForUrl}:${port}?token=domshell-singleton-probe-invalid`);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    index.ts, line 99 // .env file injects it for Path 2 / Path 3 container installs), then

  • SECRETS_ENV_READ Note

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

    index.ts, line 106 process.env.DOMSHELL_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.
