Descriptions

One of the API in Mattermost version 6.3.0 and earlier fails to properly protect the permissions, which allows the system administrators to combine the two distinct privileges/capabilities in a way that allows them to override certain restricted configurations like EnableUploads.

Una de las API de Mattermost versiones 6.3.0 y anteriores, no protege apropiadamente los permisos, lo que permite a administradores del sistema combinar los dos privilegios/capacidades distintos de forma que puedan anular determinadas configuraciones restringidas como EnableUploads
