- Unauthenticated Telegram users can inspect account information and initiate trades<![CDATA[ ## Vulnerability Details **File Location**: `simmer_weather_bot/main.py:35-39`; `simmer_weather_bot/telegram_ui.py:44-70`, `72-105`, `108-158`, `330-334` **Vulnerability Type**: Missing authentication and authorization **Risk Level**: Critical ### Vulnerable Code ```python app = ( ApplicationBuilder() .token(TELEGRAM_BOT_TOKEN) .build() ) app.add_handler(CommandHandler("start", handle_start)) app.add_handler(CommandHandler("status", handle_status)) app.add_handler(CallbackQueryHandler(handle_button, pattern="^(predict_|status)")) ``` The status handler retrieves private account information without checking the Telegram user or chat: ```python async def handle_status(update: Update, context: ContextTypes.DEFAULT_TYPE) -> None: await update.message.reply_text("⏳ Fetching agent status...") try: agent = await get_agent_info() positions = await get_positions() balance = agent.get("balance", "N/A") agent_id = agent.get("agent_id", agent.get("id", "N/A")) msg = "📊 *Agent Status*\n\n" msg += f"🆔 Agent ID: `{agent_id}`\n" msg += f"💰 Balance: `{balance}`\n" msg += f"🏦 Venue: `{SIMMER_VENUE}`\n\n" ``` The prediction callback can proceed directly to transaction execution: ```python try: trade_result = await execute_trade( market_id=market["id"], reasoning=reasoning, ) except Exception as e: await query.message.reply_text( f"⚠️ *TRADE FAILED — API error during execution*\n\n" f"📍 Market: {question[:80]}\n\n" f"Conditions were met (confidence=100%, AI=TRADE) but the trade API failed:\n" f"`{str(e)[:300]}`\n\n" f"No trade was placed.", parse_mode=ParseMode.MARKDOWN ) return ``` ### Technical Analysis The bot registers globally accessible Telegram command and callback handlers but performs no authorization check based on `update.effective_user.id`, `update.effective_chat.id`, chat type, ...[truncated 1634 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Add an explicit allowlist of permitted Telegram user IDs and, where applicable, private chat IDs. 2. Reject group and channel interactions unless they are explicitly required. 3. Apply authorization middleware to `/start`, `/status`, and all callback-query handlers. 4. Recheck authorization immediately before `execute_trade()` to prevent handler-routing or stale-callback bypasses. 5. Return a generic denial response without exposing account or market details. 6. Record denied requests with user ID, chat ID, and timestamp, without logging Telegram tokens or Simmer credentials. 7. Consider separate Telegram bots or credentials for read-only status access and transaction authority. 8. Add tests proving that unknown users cannot retrieve status, run forecasts, or execute trades. ]]>
