PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/index.ts, line 151 await fs.unlink(AUTH_INFO_PATH);

  • NETWORK_NO_FIXED_HOST Low

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

    src/test-utils/setup.ts, line 70 http.get("https://graph.microsoft.com/v1.0/me", () => {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/test-utils/setup.ts, line 70 http.get("https://graph.microsoft.com/v1.0/me", () => {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 31 .env

  • SECRETS_ENV_READ Note

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

    src/server.ts, line 40 if (!readOnly && !process.env.AUTH_TOKEN) {

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    package-lock.json, line 1 {

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.
