Descriptions
Mattermost fails to check if hardened mode is enabled when overriding the username and/or the icon when posting a post. If settings allowed integrations to override the username and profile picture when posting, a member could also override the username and icon when making a post even if the Hardened Mode setting was enabled
Mattermost no verifica si el modo reforzado está habilitado al anular el nombre de usuario y/o el ícono al publicar una publicación. Si la configuración permitía que las integraciones anularan el nombre de usuario y la imagen de perfil al publicar, un miembro también podría anular el nombre de usuario y el ícono al realizar una publicación, incluso si la configuración del Hardened Mode estaba habilitada.
