Grades are a hygiene check, not a security guarantee.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit a3a3289ca4b6, unchanged since the check below.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    main.go, line 67 return errors.New("TRILIUM_URL and TRILIUM_TOKEN must be set (via env or .env file)")

  • PERMISSION_SHELL_DECLARED Note

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

    e2e/test_e2e.py, line 10 self.p = subprocess.Popen([BIN], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, bufsize=1, text=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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    e2e/test_e2e.py, line 10

    self.p = subprocess.Popen([BIN], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, bufsize=1, text=True)

    e2e/test_v014.py, line 10

    self.p = subprocess.Popen([BIN], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, bufsize=1, text=True)

  • Install and update

    Pass

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

  • Network

    Pass

    No network call found.

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_PATH_DOTENV

    main.go, line 67

    return errors.New("TRILIUM_URL and TRILIUM_TOKEN must be set (via env or .env file)")

    .gitignore, line 1

    .env

    README.md, line 80

    Copy `.env.example` to `.env` next to the binary:

    Show more

    README.md, line 194

    - The server reads `TRILIUM_TOKEN` from env. Treat it like a password - anyone with it can read and write your entire KB. Keep `.env` out of git (it is in `.gitignore`).

  • Agent instructions

    Pass

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

  • Obfuscation

    Pass

    No encoded or minified payload found.

  • Licence

    Pass

    A licence file is present (LICENSE).

  • Maintainer activity

    Pass
