Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    internal/bridge/daemon.go, line 88 cmd := exec.CommandContext(childCtx, d.command, d.args...)

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 23 KAAS_VERSION="$(curl -fsSI "https://github.com/${REPO}/releases/latest" 2>/dev/null \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .dockerignore, line 14 .env

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    README.md, line 108 curl -fsSL https://raw.githubusercontent.com/bybit-exchange/kaas/main/install.sh | sh

  • SECRETS_ENV_READ Note

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

    internal/config/config.go, line 286 if v := os.Getenv("KAAS_MCP_TOKEN"); v != "" {

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    docs/features/derive-topic-kb-from-catalog/plan.md, line 1 # Derive a topic-scoped knowledge base - implementation plan

  • OBFUSCATION_FILE_CAP_REACHED Note

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

    docs/features/derive-topic-kb-from-catalog/plan.md, line 1 # Derive a topic-scoped knowledge base - implementation plan

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.

    This is backwards-compatible - all existing callers that pass only `id` continue to work. The `apiFetch` function already passes through `init` (including `signal`) to `fetch()`.
