Rescanned at commit 2ed0c2e71d4a.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/smoke-cli.mjs, line 238 fs.rmSync(smokeRoot, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    browser-extension/service-worker.js, line 149 const ws = new WebSocket(`ws://127.0.0.1:${bridgePort}/extension`);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src-tauri/src/policy.rs, line 190 "head /srv/app/.env | grep TOKEN",

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.
