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.

    apps/desktop/scripts/build-icons.mjs, line 39 fs.rmSync(iconset, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    apps/desktop/src/main/index.ts, line 1319 fetchImpl: (input, init) => fetch(input, init),

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    AGENTS.md, line 336 - Never commit `.env` files or notarization credentials. The manual release

  • SECRETS_ENV_READ Note

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

    apps/desktop/src/main/ai.test.ts, line 533 const googleStubKey = process.env.GOOGLE_STUB_KEY ?? "google-stub-key";

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    THIRD_PARTY_NOTICES.md, line 1 # PromptBranch - Third-Party Notices

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.
