Rescanned at commit fd578b94685e, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 27 @ai-sdk/google

  • NETWORK_NO_FIXED_HOST Low

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

    src/collab/writeback.ts, line 34 const res = await fetch(`${collabUrl}/_internal/writeback/${docId}`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/collab/writeback.ts, line 34 const res = await fetch(`${collabUrl}/_internal/writeback/${docId}`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/config/env.ts, line 7 // Walk up from this file to find the nearest .env (repo root or app root).

  • SECRETS_ENV_READ Note

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

    scripts/mint-test-jwt.mjs, line 5 const secret = new TextEncoder().encode(process.env.JWT_SECRET);

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    src/tests/round-trip/fuzz.test.ts, line 1 import { describe, expect, it } from 'vitest';

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

    Pass
