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

Rescanned at commit f0bf811c0716, unchanged since the check below.

INSTALL_UNPINNED NETWORK_LOCALHOST SECRETS_ENV_READ

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 11 @coinbase/x402

  • NETWORK_LOCALHOST Note

    Calls localhost only.

    src/shared.ts, line 385 resp = await fetch(`http://localhost:${port}${route.path}${qs ? "?" + qs : ""}`, { headers });

  • SECRETS_ENV_READ Note

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

    src/index.ts, line 27 process.env.CDP_API_KEY_ID!,

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.
