Fleet is open source device management software. Prior to 4.81.1, a broken access control vulnerability in Fleet's host transfer API allows a team maintainer to transfer hosts from any team into their own team, bypassing team isolation boundaries. Once transferred, the attacker gains full control over the stolen hosts, including the ability to execute scripts with root privileges. Version 4.81.1 patches the issue.

A Fleet team maintainer can transfer hosts from any team via missing source team authorization
### Summary
A broken access control vulnerability in Fleet's host transfer API allows a team maintainer to transfer hosts from any team into their own team, bypassing team isolation boundaries. Once transferred, the attacker gains full control over the stolen hosts, including the ability to execute scripts with root privileges.
### Impact
The host transfer endpoints verify that the caller has write permission to the destination team but do not check whether the caller has any permission over the source team of the hosts being transferred.
Once hosts are transferred, the attacker's team MDM configuration is automatically applied to the stolen devices, and the attacker can execute scripts on t
