Descriptions

Mattermost fails to check whether the  “Allow users to view archived channels”  setting is enabled during permalink previews display, allowing members to view permalink previews of archived channels even if the “Allow users to view archived channels” setting is disabled.

Mattermost no verifica si la configuración "Permitir a los usuarios ver canales archivados" está habilitada durante la visualización de vistas previas de enlaces permanentes, lo que permite a los miembros ver vistas previas de enlaces permanentes de canales archivados incluso si la configuración "Permitir a los usuarios ver canales archivados" está deshabilitada.
