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

Rescanned at commit 17b6302f1617, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    client-identity.test.js, line 54 const ws = new WebSocket(`ws://127.0.0.1:${port}`)

  • SECRETS_ENV_READ Note

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

    uivision-mcp-bridge.js, line 124 const explicit = argValue('--token') || process.env.UIVISION_MCP_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.
