CVE-2026-66027

Suna before 0.9.102 contains a broken access control vulnerability in the message queue API that allows authenticated attackers to access and manipulate queue resources belonging to other users by exploiting missing ownership and account isolation checks. Attackers can read pending prompt queues of all users, read or delete individual sessions, and inject arbitrary prompts into another user's session queue, causing the background drainer to forward malicious messages to the victim's running AI agent with the victim's credentials and permissions.

Summary		(es) Suna anterior a la versión 0.9.102 contiene una vulnerabilidad de control de acceso roto en la API de cola de mensajes que permite a atacantes autenticados acceder y manipular recursos de cola pertenecientes a otros usuarios al explotar la falta de comprobaciones de propiedad y aislamiento de cuentas. Los atacantes pueden leer las colas de prompts pendientes de todos los usuarios, leer o eliminar sesiones individuales, e inyectar prompts arbitrarios en la cola de sesión de otro usuario, lo que hace que el drenador en segundo plano reenvíe mensajes maliciosos al agente de IA en ejecución de la víctima con las credenciales y permisos de la víctima.
