Descriptions

Mattermost fails to check the required permissions in the POST /api/v4/channels/stats/member_count API resulting in channel member counts being leaked to a user without permissions.

Mattermost no verifica los permisos requeridos en la API POST /api/v4/channels/stats/member_count, lo que provoca que los recuentos de miembros del canal se filtren a un usuario sin permisos.
