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.

    bench/lib/common.mjs, line 59 fs.rmSync(dir, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    bench/e2e-ollama.mjs, line 74 const res = await fetch(url, { ...opts, signal: ctrl.signal });

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    bench/e2e-ollama.mjs, line 74 const res = await fetch(url, { ...opts, signal: ctrl.signal });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    desktop/src-tauri/src/sidecar.rs, line 273 .env("NODE_PATH", &node_modules_s)

  • SECRETS_ENV_READ Note

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

    bin/engram.js, line 793 const key = process.env.ENGRAM_DB_KEY;

  • 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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    bench/lib/common.mjs, line 59

    fs.rmSync(dir, { recursive: true, force: true });

    src/memory/store.js, line 116

    if (fs.existsSync(sidecar)) fs.rmSync(sidecar, { force: true });

    src/skill/install.js, line 156

    fs.rmSync(dest, { recursive: true, force: true });

  • 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.npmjs.org. The description does not name that host.
