Descriptions

Mattermost fails to properly restrict the access of files attached to posts in an archived channel, resulting in members being able to access files of archived channels even if the “Allow users to view archived channels” option is disabled.

Mattermost no logra restringir adecuadamente el acceso a los archivos adjuntos a las publicaciones en un canal archivado, lo que hace que los miembros puedan acceder a los archivos de los canales archivados incluso si la opción "Permitir a los usuarios ver canales archivados" está deshabilitada.
