      "value": "PraisonAI AgentMail versions before 4.6.78 lack signature verification in webhook mode, allowing unauthenticated attackers to inject messages with spoofed sender addresses. Attackers can POST crafted message.received events to the webhook endpoint to inject arbitrary content into the agent and trigger replies to attacker-controlled addresses, bypassing sender allow/block lists."

      "value": "Las versiones de PraisonAI AgentMail anteriores a la 4.6.78 carecen de verificación de firma en modo webhook, lo que permite a atacantes no autenticados inyectar mensajes con direcciones de remitente falsificadas. Los atacantes pueden enviar (POST) eventos message.received manipulados al endpoint del webhook para inyectar contenido arbitrario en el agente y activar respuestas a direcciones controladas por el atacante, eludiendo las listas de remitentes permitidos/bloqueados."
