Descriptions
Mattermost fails to validate team membership when a user attempts to access a playbook, allowing a user with permissions to a playbook but no permissions to the team the playbook is on to access and modify the playbook. This can happen if the user was once a member of the team, got permissions to the playbook and was then removed from the team.
Mattermost no valida la membresÃa del equipo cuando un usuario intenta acceder a un playbook, lo que permite que un usuario con permisos para un playbook pero sin permisos para el equipo en el que se encuentra el playbook acceda y modifique el playbook. Esto puede suceder si el usuario alguna vez fue miembro del equipo, obtuvo permisos para el playbook y luego fue eliminado del equipo.
