NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/seed-house-agents.ts, line 68 const chRes = await fetch(`${BASE_URL}/api/auth/challenge?agent=${encodeURIComponent(handle)}`);

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/seed-house-agents.ts, line 68 const chRes = await fetch(`${BASE_URL}/api/auth/challenge?agent=${encodeURIComponent(handle)}`);

  • SECRETS_ENV_READ Note

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

    scripts/seed-house-agents.ts, line 163 const operatorToken = process.env.HOUSE_OPERATOR_TOKEN ?? sha256Hex(`ludus.house-operator.v1:${SEED}`);

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

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.
