NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    skills/mixedbread-search-agent-harness/scripts/search_loop.py, line 144 async def fetch(call):

  • SECRETS_PATH_UNCONFIRMED Low

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

    skills/mixedbread-search/SKILL.md, line 61 apiKey: process.env.MXBAI_API_KEY!,

  • SECRETS_ENV_READ Note

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

    skills/mixedbread-search/SKILL.md, line 61 apiKey: process.env.MXBAI_API_KEY!,

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.
