Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
When TELEGRAM_WEBHOOK_URL was set but TELEGRAM_WEBHOOK_SECRET was not,
python-telegram-bot received secret_token=None and the webhook endpoint
accepted any HTTP POST. Anyone who could reach the listener could inject
forged updates — spoofed user IDs, spoofed chat IDs, attacker-controlled
message text — and trigger handlers as if Telegram delivered them.
The fix refuses to start the adapter in webhook mode without the secret.
Polling mode (default, no webhook URL) is unaffected — polling is
authenticated by the bot token directly.
BREAKING CHANGE for webhook-mode deployments that never set
TELEGRAM_WEBHOOK_SECRET. The error message explains remediation:
export TELEGRAM_WEBHOOK_SECRET="$(openssl rand -hex 32)"
and instructs registering it with Telegram via setWebhook's secret_token
parameter. Release notes must call this out.
Reported in GHSA-3vpc-7q5r-276h by @bupt-Yy-young. Hardening — not CVE
per SECURITY.md §3 "Public Exposure: Deploying the gateway to the
public internet without external authentication or network protection"
covers the historical default, but shipping a fail-open webhook as the
default was the wrong choice and the guard aligns us with the SECURITY.md
threat model.
