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

Rescanned at commit b6c52abb3d33, 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/path-policy.ts, line 29 const HOME_CREDENTIAL_FILES = [[".netrc"], [".npmrc"], [".pypirc"], [".git-credentials"]] as const;

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.
