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

Rescanned at commit d6f033d1335d, unchanged since the check below.

SECRETS_PATH_CREDENTIAL

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    src/index.ts, line 170 'Diagnostic tool - shows which registry URL and auth credentials the server resolves for a given package name based on ~/.npmrc. Useful for debugging private registry access.',

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.
