I've uploaded the patched nodejs to the Bionic queue, as well as discussed it in #ubuntu-release; the SRU approvers will either accept or reject it now, and I (or someone) will still need to go through all the Ubuntu packages that have a dependency on nodejs, to check which (if any) will need to be rebuilt with the new nodejs (since the ABI will be different).
