INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 5 hnswlib>=0.8.0,<1.0.0

  • NETWORK_NO_FIXED_HOST Low

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

    bootstrap.py, line 56 cli-ux-003: replaces the old ``curl -s .../api/tags`` shell-out. Reuses

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    bootstrap.py, line 239 "TOOL_COMPASS_EMBEDDING_API_KEY (see .env.example)"

  • PERMISSION_SHELL_DECLARED Note

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

    bootstrap.py, line 25 result = subprocess.run(cmd, shell=True, capture_output=True, text=True)

  • SECRETS_ENV_READ Note

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

    config.py, line 960 raw_api_key = os.environ.get("TOOL_COMPASS_EMBEDDING_API_KEY")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    atlas/structure.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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    bootstrap.py, line 25

    result = subprocess.run(cmd, shell=True, capture_output=True, text=True)

    bootstrap.py, line 43

    result = subprocess.run(argv, capture_output=True, text=True)

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    requirements.txt, line 5

    hnswlib>=0.8.0,<1.0.0

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    bootstrap.py, line 56

    cli-ux-003: replaces the old ``curl -s .../api/tags`` shell-out. Reuses

    bootstrap.py, line 60

    No curl dependency; works on Windows where curl may be absent from PATH.

    test: ["CMD", "python", "-c", "import urllib.request; urllib.request.urlopen('http://localhost:7860')"]

  • Secrets

    Concern

    reads a credential or environment file.
