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

Rescanned at commit cc58fe3d3757.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_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.

    src/cli.ts, line 1338 fs.unlinkSync(CONFIG_FILE);

  • NETWORK_NO_FIXED_HOST Low

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

    docker/forward-port.mjs, line 5 const upstream = net.connect({ host: "affine", port: 3010 });

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 9 .env

  • SECRETS_ENV_READ Note

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

    test-comprehensive.mjs, line 15 const PASSWORD = process.env.AFFINE_PASSWORD || process.env.AFFINE_ADMIN_PASSWORD;

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    src/tools/docs.ts, line 1 import { isDeepStrictEqual } from "node:util";

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

    src/cli.ts, line 1338

    fs.unlinkSync(CONFIG_FILE);

    src/config.ts, line 108

    try { fs.unlinkSync(tmpFile); } catch {}

  • 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.

    NETWORK_NO_FIXED_HOST

    docker/forward-port.mjs, line 5

    const upstream = net.connect({ host: "affine", port: 3010 });

    src/oauth.ts, line 48

    signal => fetch(input, {

    src/stdioHttpProxy.ts, line 92

    signal => fetch(input, { ...init, signal }),

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_DOTENV

    test-comprehensive.mjs, line 15

    const PASSWORD = process.env.AFFINE_PASSWORD || process.env.AFFINE_ADMIN_PASSWORD;

    scripts/test-append-block-expansion.mjs, line 10

    const PASSWORD = process.env.AFFINE_PASSWORD || 'dev';

    .gitignore, line 9

    .env

    Show more

    src/config.ts, line 254

    const environmentHasPassword = Boolean(process.env.AFFINE_PASSWORD);

    src/sse.ts, line 103

    process.env.AFFINE_MCP_HTTP_ALLOW_QUERY_TOKEN,

    src/stdioHttpProxy.ts, line 20

    const token = process.env.AFFINE_MCP_HTTP_TOKEN?.trim();

    CHANGELOG.md, line 845

    - Documentation: removed `.env`-based configuration guidance; recommend environment variables via shell or app configuration.

    CHANGELOG.md, line 859

    - Unnecessary repo artifacts (e.g., `.env.example`, `.dockerignore`).

  • Agent instructions

    Pass

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

  • Obfuscation

    Note

    OBFUSCATION_FILE_OVER_READ_CAP

    src/tools/docs.ts, line 1
