Prior to version 4.6.40, PraisonAI's call server exposes a network-facing agent control API without authentication when `CALL_SERVER_TOKEN` is not configured. The affected component is the `praisonai.api.agent_invoke` router as mounted by `praisonai.api.call`. The authentication helper `verify_token()` fails open when `CALL_SERVER_TOKEN` is unset. Since every sensitive agent-control endpoint depends on this helper, starting the call server without a token allows any reachable client to list agents, inspect agent metadata and instructions, invoke agents, and unregister agents. This is security-relevant because the bundled call server includes the vulnerable router and binds to `0.0.0.0`. As a result, operators who launch the call server without explicitly setting `CALL_SERVER_TOKEN` may unintentionally expose an unauthenticated remote agent control plane. Version 4.6.40 fixes the issue."}, {"lang": "es", "value": "PraisonAI es un sistema de equipos multiagente. Antes de la versi\u00f3n 4.6.40, el servidor de llamadas de PraisonAI expone una API de control de agente orientada a la red sin autenticaci\u00f3n cuando \u2019CALL_SERVER_TOKEN\u2019 no est\u00e1 configurado. El componente afectado es el router \u2019praisonai.api.agent_invoke\u2019 tal como lo monta \u2019praisonai.api.call\u2019. El asistente de autenticaci\u00f3n \u2019verify_token()\u2019 falla en modo abierto cuando \u2019CALL_SERVER_TOKEN\u2019 no est\u00e1 establecido. Dado que cada endpoint sensible de control de agente depende de este asistente, iniciar el servidor de llamadas sin un token permite a cualquier cliente alcanzable listar agentes, inspeccionar metadatos e instrucciones de agentes, invocar agentes y anular el registro de agentes. Esto es relevante para la seguridad porque el servidor de llamadas incluido incluye el router vulnerable y se enlaza a \u20190.0.0.0\u2019. Como resultado, los operadores que inician el servidor de llamadas sin establecer expl\u00edcitamente \u2019CALL_SERVER_TOKEN\u2019 pueden exponer involuntariamente un plano de control de agente remoto no autenticado.
