GHSA-m65r-rprj-r5rg - Handler channel callbacks called for non-existing channel - 7c5659f
Russh server did not validate channel IDs passed by a client, so if a client constructed a channel message with an invalid ID, the server-side Handler callback would still get called with that non-existing ID. The consequence of this depend on the specific user implementation.
