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

Rescanned at commit 969ff2ce0acf.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 53 @e2a/sdk

  • NETWORK_NO_FIXED_HOST Low

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

    src/readyz.ts, line 20 const res = await fetch(url, { signal: AbortSignal.timeout(timeoutMs) });

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.
