Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    mcp/server.mcp.mjs, line 196 if (f.endsWith('.lock')) fs.rmSync(path.join(avdDir, f), { force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    mcp/server.mcp.mjs, line 446 const sock = new WebSocket(relayEndpoint(info), { rejectUnauthorized: false });

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    web/server.js, line 48 const WEB_CONTROL_TOKEN = process.env.WEB_CONTROL_TOKEN || null;

  • SECRETS_ENV_READ Note

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

    web/server.js, line 48 const WEB_CONTROL_TOKEN = process.env.WEB_CONTROL_TOKEN || null;

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.
