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

Rescanned at commit 0a56c120d8b2, 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/lib/flightCheck.ts, line 51 re: /(~\/\.(ssh|aws|gnupg|config\/gcloud|claude)|\bid_rsa\b|\.env\b(?!\.example)|credentials\.json)/i },

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.
