Descriptions

Mattermost versions 9.5.x <= 9.5.3, 9.7.x <= 9.7.1, 9.6.x <= 9.6.1, 8.1.x <= 8.1.12 fail to enforce proper access control which allows a user to run a slash command in a channel they are not a member of via linking a playbook run to that channel and running a slash command as a playbook task command.

Las versiones de Mattermost 9.5.x <= 9.5.3, 9.7.x <= 9.7.1, 9.6.x <= 9.6.1, 8.1.x <= 8.1.12 no aplican el control de acceso adecuado que permite a un usuario ejecutar un comando de barra diagonal en un canal del que no son miembros vinculando una ejecución del libro de jugadas a ese canal y ejecutando un comando de barra diagonal como un comando de tarea del libro de jugadas.
