Grades are a hygiene check, not a security guarantee.

Grade B

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

Graded by PlugVetRubric v2

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

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/check-snapshot.mjs, line 49 const res = await fetch(`https://api.github.com/repos/${UPSTREAM_REPO}/commits/${sha}`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/check-snapshot.mjs, line 49 const res = await fetch(`https://api.github.com/repos/${UPSTREAM_REPO}/commits/${sha}`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/format.test.ts, line 25 assert.equal(safeAttachmentFilename(".env"), "env");

  • SECRETS_ENV_READ Note

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

    scripts/check-snapshot.mjs, line 48 if (process.env.GITHUB_TOKEN) headers.authorization = `Bearer ${process.env.GITHUB_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.
