SECRETS_PATH_CREDENTIAL

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

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

    .github/workflows/test.yml, line 38 FOUND=$(tar -tzf "$SDIST" | grep -E '(/\.claude/|/\.env(\.|$)|/\.pypirc|/\.aws/|/\.ssh/|/id_rsa|/id_ed25519|\.pem$|\.key$|/credentials\.(json|yaml|yml|conf|cfg|ini|env)$|/aws_?cred

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.
