Rebalancing requires routing transactions through other nodes, subject to fees. If the wallet is unable to assess the route selected, a compromised node could be made to select attacker-controlled, high-fee routes as a means of extracting funds.

Sure and once the rebalancing funds are out the node will stop. Which is a good thing if it's compromised. Lightning fees are supposed to be very very low so this fund would probably run out after a few dollars worth making this kind of attack very low reward. A node should be able to rebalance by just adjusting its own fee structure most of the time.
