NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    collector/dashboard/app.js, line 147 const response = await fetch(`/api/metrics?${params}`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    collector/dashboard/app.js, line 147 const response = await fetch(`/api/metrics?${params}`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .dockerignore, line 34 .env

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    docs/plans/task-5-oauth-flow.md, line 23 - **`node:child_process.exec` for browser open** — Uses platform-specific commands (`open` on macOS, `xdg-open` on Linux, `start` on Windows) to open the authorization URL. This is

  • SECRETS_ENV_READ Note

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

    src/index.ts, line 212 const connectorPassword = process.env.MCP_CONNECTOR_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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    docs/plans/task-5-oauth-flow.md, line 23

    - **`node:child_process.exec` for browser open** — Uses platform-specific commands (`open` on macOS, `xdg-open` on Linux, `start` on Windows) to open the authorization URL. This is

    docs/plans/task-5-oauth-flow.md, line 331

    - [ ] Tests mock `child_process.exec` — no real browser opens

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.prod.whoop.com. The description does not name that host.

    NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST

    response = await fetch(WHOOP_TOKEN_URL, {

    src/dashboard/static/app.js, line 91

    response = await fetch(`${path}${query}`, init);

  • Secrets

    Concern

    reads a credential or environment file.

    const connectorPassword = process.env.MCP_CONNECTOR_PASSWORD;

    const envSecret = process.env.WHOOP_CLIENT_SECRET?.trim() ?? "";

    src/cli/setup.ts, line 410

    process.env.WHOOP_CLIENT_SECRET = clientSecret;

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Concern

    contains an encoded blob in a file that should be readable.
