🚧 Version 0.1.10 — the rest of an outside review, and a fix that was too blunt Published: binaries for five platforms with checksums, Sigstore signatures and build provenance; .mcpb bundles for one-click install; an image on ghcr.io for amd64 and arm64; a package

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

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

Rescanned at commit b1909e9443dd, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    npm/lib/install.js, line 122 fs.rmSync(tmp, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    npm/lib/install.js, line 72 const res = await fetch(url, { redirect: 'follow' });

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    npm/lib/install.js, line 72 const res = await fetch(url, { redirect: 'follow' });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/authz.rs, line 18 /// Both spellings occur in the wild - a Kubernetes secret mounts a file, a `.env` inlines the text -

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.
