Details
As written in the advisory (Markdown source, shown as plain text).
Mattermost versions 9.11.x <= 9.11.5 fail to enforce invite permissions, which allows team admins, with no permission to invite users to their team, to invite users by updating the "allow_open_invite" field via making their team public.
