      "value": "AgenticMail gives AI agents real email addresses and phone numbers. In @agenticmail/api prior to version 0.9.64, a low-privileged authenticated AgenticMail agent can enumerate another agent's pending/claimed tasks by supplying the target agent name to `GET /api/agenticmail/tasks/pending?assignee=<name>`. The returned task objects include the task IDs and payloads. The same task IDs can then be used with the capability-style task mutation endpoints (`/tasks/:id/claim`, `/tasks/:id/result`, `/tasks/:id/complete`, `/tasks/:id/fail`) to claim, complete, or fail tasks assigned to a different agent. Because ordinary authenticated agents can discover agent names through `GET /api/agenticmail/accounts/directory`, the task ID effectively stops being a secret capability. This turns the intended capability model into a cross-agent authorization bypass. Version 0.9.64 contains a fix."

      "value": "AgenticMail proporciona a los agentes de IA direcciones de correo electrónico y números de teléfono reales. En @agenticmail/api, anterior a la versión 0.9.64, un agente de AgenticMail autenticado con bajos privilegios puede enumerar las tareas pendientes/reclamadas de otro agente al proporcionar el nombre del agente objetivo a GET /api/agenticmail/tasks/pending?assignee=[name]. Los objetos de tarea devueltos incluyen los ID de tarea y las cargas útiles. Los mismos ID de tarea pueden luego ser utilizados con los puntos finales de mutación de tareas de estilo de capacidad (/tasks/:id/claim, /tasks/:id/result, /tasks/:id/complete, /tasks/:id/fail) para reclamar, completar o fallar tareas asignadas a un agente diferente. Debido a que los agentes autenticados ordinarios pueden descubrir nombres de agentes a través de GET /api/agenticmail/accounts/directory, el ID de tarea deja de ser efectivamente una capacidad secreta. Esto convierte el modelo de capacidad previsto en una omisión de autorización entre agentes. La versión 0.9.64 contiene una corrección."
