# AFTER (SECURE):
command: jupyter lab --ip=0.0.0.0 --port=8888 --no-browser --allow-root
environment:
  - JUPYTER_TOKEN=${JUPYTER_TOKEN:-$(openssl rand -hex 32)}

Fix 2: Replace Pickle (30 minutes)

File: tradingagents/backtest/data_handler.py:308

# BEFORE (VULNERABLE):
with open(cache_file, 'rb') as f:
    return pickle.load(f)  # UNSAFE!

# AFTER (SECURE):
def _save_to_cache(self, ticker, data, start_date, end_date):
    cache_file = self._cache_dir / f"{ticker}_{start_date}_{end_date}.parquet"
    data.to_parquet(cache_file)

def _load_from_cache(self, ticker, start_date, end_date):
    cache_file = self._cache_dir / f"{ticker}_{start_date}_{end_date}.parquet"
    if cache_file.exists():
        return pd.read_parquet(cache_file)
    return None

Fix 3: Add Rate Limiting (1 hour)

File: tradingagents/brokers/alpaca_broker.py

from tradingagents.security import RateLimiter

class AlpacaBroker(BaseBroker):
    def __init__(self, ...):
        super().__init__(paper_trading)
        # Alpaca limit: 200 requests/minute
        self._rate_limiter = RateLimiter(max_calls=200, period=60)
        self._session = requests.Session()

    def _api_request(self, method: str, url: str, **kwargs):
        """Make rate-limited API request."""
        @self._rate_limiter
        def _call():
            return self._session.request(method, url, **kwargs)
        return _call()

    # Update all methods to use _api_request instead of requests.get/post/etc

Fix 4: Pin Dependencies (30 minutes)

File: requirements.txt

# Run this to generate pinned versions:
pip freeze > requirements.txt

# Or manually specify:
requests==2.32.5
pandas==2.3.3
numpy==1.26.4
langchain-openai==0.2.11
langchain-anthropic==0.1.23
langchain-google-genai==1.0.10
chainlit==1.3.1
pytest==8.3.4
# ... etc for all dependencies

Fix 5: Docker Non-Root User (15 minutes)

File: Dockerfile

# Add before CMD:
RUN useradd -m -u 1000 tradingagents && \
    chown -R tradingagents:tradingagents /app /app/data /app/eval_results /app/portfolio_data

USER tradingagents

Fix 6: Input Validation (2 hours)

File: web_app.py

from tradingagents.security import validate_ticker
from decimal import Decimal, InvalidOperation

async def main(message: cl.Message):
    msg_content = message.content.strip()
    parts = msg_content.split()

    if not parts:
        await cl.Message(content="Please enter a command.").send()
        return

    command = parts[0].lower()

    # Analyze command
    if command == "analyze":
        if len(parts) < 2:
            await cl.Message(content="Usage: `analyze TICKER`").send()
            return

        try:
            ticker = validate_ticker(parts[1])  # ADD VALIDATION
            await analyze_stock(ticker)
        except ValueError as e:
            await cl.Message(content=f"Invalid ticker: {e}").send()

    # Buy command
    elif command == "buy":
        if len(parts) < 3:
            await cl.Message(content="Usage: `buy TICKER QUANTITY`").send()
            return

        try:
            ticker = validate_ticker(parts[1])  # ADD VALIDATION
            quantity = Decimal(parts[2])

            # VALIDATE QUANTITY
            if quantity <= 0:
                raise ValueError("Quantity must be positive")
            if quantity > Decimal('100000'):
                raise ValueError("Quantity too large (max 100,000)")

            await execute_buy(ticker, quantity)

        except (ValueError, InvalidOperation) as e:
            await cl.Message(content=f"Invalid input: {e}").send()

    # Apply same pattern to sell command

Fix 7: Thread Safety (1 hour)

File: web_app.py:26-27

# BEFORE (UNSAFE):
ta_graph: Optional[TradingAgentsGraph] = None
broker: Optional[AlpacaBroker] = None

# AFTER (SAFE):
# Remove global variables, use session storage

@cl.on_chat_start
async def start():
    cl.user_session.set("ta_graph", None)
    cl.user_session.set("broker", None)
    cl.user_session.set("config", DEFAULT_CONFIG.copy())

async def analyze_stock(ticker: str):
    # Get from session instead of global
    ta_graph = cl.user_session.get("ta_graph")

    if ta_graph is None:
        config = cl.user_session.get("config")
        ta_graph = TradingAgentsGraph(config=config)
        cl.user_session.set("ta_graph", ta_graph)

    # ... rest of function

# Apply same pattern to all functions using global state

Fix 8: Return Type Hints (2 hours)

Add to all functions in:

tradingagents/llm_factory.py
tradingagents/brokers/alpaca_broker.py
web_app.py

from typing import Optional, List, Union
from langchain_openai import ChatOpenAI
from langchain_anthropic import ChatAnthropic
from langchain_google_genai import ChatGoogleGenerativeAI

LLMType = Union[ChatOpenAI, ChatAnthropic, ChatGoogleGenerativeAI]

@staticmethod
def create_llm(
    provider: str,
    model: str,
    temperature: float = 1.0,
    max_tokens: Optional[int] = None,
    backend_url: Optional[str] = None,
    **kwargs
) -> LLMType:  # ADD THIS
    ...

def connect(self) -> bool:  # ADD THIS
    ...
