Fleet before 4.89.0 contains an unbounded recursion vulnerability in Apple MDM enrollment property list parsing that allows unauthenticated attackers to crash the server. Attackers can send a crafted binary plist payload of about 150 bytes to the enrollment endpoints, triggering exponential allocation or infinite recursion that exhausts CPU and memory.
