fleetdm/fleet is an open source device management, built on osquery. All versions of fleet making use of the teams feature are affected by this authorization bypass issue. Fleet instances without teams, or with teams but without restricted team accounts are not affected. In affected versions a team admin can erroneously add themselves as admin, maintainer or observer on other teams. Users are advised to upgrade to version 4.13. There are no known workarounds for this issue.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
