Descriptions
The Guest account feature in Mattermost version 6.7.0 and earlier fails to properly restrict the permissions, which allows a guest user to fetch a list of all public channels in the team, in spite of not being part of those channels.
La función de cuenta de invitado en Mattermost versiones 6.7.0 y anteriores no restringe apropiadamente los permisos, lo que permite a un usuario invitado conseguir una lista de todos los canales públicos del equipo, a pesar de no formar parte de esos canales
