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

Rescanned at commit aff6880435ab, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/auth/login.ts, line 205 fs.unlinkSync(SESSION_FILE);

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    scripts/claim-npm-names.sh, line 53 [[ "$(curl -s -o /dev/null -w '%{http_code}' "https://registry.npmjs.org/$1")" == "404" ]]

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/claim-npm-names.sh, line 53 [[ "$(curl -s -o /dev/null -w '%{http_code}' "https://registry.npmjs.org/$1")" == "404" ]]

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    fix-for-release.sh, line 84 .env

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/cli-complete.ts, line 33 const password = options.password || process.env.SAINSBURYS_PASSWORD;

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.
