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

Rescanned at commit c44317fd6ddf, unchanged since the check below.

INSTALL_LIFECYCLE_HOOK SECRETS_PATH_CREDENTIAL

Why this grade

  • INSTALL_LIFECYCLE_HOOK Medium

    A package install hook (preinstall, install, postinstall or prepare) runs a script.

    package.json, line 45 prepare

  • SECRETS_PATH_CREDENTIAL Medium

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

    packages/core/src/core.test.ts, line 30 expect(isSecretPath("certs/id_rsa")).toBe(true);

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.
